Interview with satellite positioning experts: centimeter-level positioning, how big a sky can the quasi-zenith top?

  Chen Chao, correspondent of Science and Technology Daily in Japan

  Not long ago, Japan launched the fourth Quasi-Zenith System (QZSS) "Pathfinder" 4 satellite that can be used for satellite navigation and positioning, and its announced centimeter-level positioning accuracy has attracted widespread attention. Regarding the latest progress of Quasi-Zenith satellites, a reporter from Science and Technology Daily interviewed satellite positioning expert Liu Zhixing, a visiting professor at York University in Canada.

  Three characteristics of quasi-zenith system

  Liu Zhixing first introduced that the quasi-zenith system has three satellites in tilt-synchronous orbit working over Japan, rotating alternately for 8 hours, so as to ensure that a satellite with a higher elevation angle is on duty in Japan’s "zenith" at any time, which makes it possible for this satellite, which will not be blocked, to "supplement" GPS’s positioning ability in harsh environments in urban centers and valleys. The successful launch of the No. 4 satellite will, together with the three satellites launched before, form a regional satellite navigation and positioning assistance enhancement system that can cover Japan and the surrounding area. Now Quasi-zenith is in the practice run stage. It will officially provide services to Japan and surrounding areas in 2018, and increase to seven satellites in 2023. It is possible to expand into a regional navigation system that does not rely on GPS and operates independently.

  Secondly, the positioning accuracy is enhanced. Quasi-Zenith satellites provide two GPS enhancement signals: L1S and L1Sb (starting to provide SBAS satellite-based enhancement services in 2020) can provide sub-meter-level positioning accuracy enhancement services, enabling users in Japan to improve their positioning accuracy from 10 meters when relying only on GPS to about 1 meter; the other is centimeter-level enhancement signal L6, including L6D and L6E, which can perform precise single-point positioning.

  Finally, the quasi-zenith system can also provide warning services, including disaster warnings such as earthquakes and tsunamis; when GPS satellites are abnormal, users can also be notified in time to avoid wrong positioning.

  Positioning accuracy up to 6 cm

  According to Japanese media reports, the positioning accuracy of the quasi-zenith system can reach 6 cm after the deployment of the first phase, including three tilt-synchronous orbit satellites and one geosynchronous orbit satellite. What technology is used to achieve this order of magnitude difference?

  Liu Zhixing explained that the centimeter-level positioning accuracy that the quasi-zenith satellite navigation system can achieve is achieved by the enhancement of GPS by the L6 signal. The precision single-point positioning provided by it is a key technology for achieving global precision real-time dynamic positioning and navigation. It is also a cutting-edge research direction in global navigation satellite system (GNSS) positioning, but it is not unique to Japan. In application, the L6 signal is not compatible with GPS signals, and special receivers and antennas are required for reception. It can be used in high-precision measurement, high-precision construction of construction machinery, and IT precision agriculture. Due to the large size of the antenna and receiver, it cannot be compared with mobile end points such as mobile phones. At this stage, it can only be used for measuring instruments and vehicles.

  Quasi-Zenith Technical Advantages and Controversies

  By 2023, when the number of Quasi-Zenith satellites reaches 7, it will have the ability to work independently from the GPS system and become Japan’s regional satellite navigation system. This process provides an in-orbit platform for testing and demonstration, which will greatly promote Japan’s independent research and development capabilities in the field of satellite navigation. However, in terms of applications, some media have pointed out that because Quasi-Zenith is a regional system, it cannot be popularized and may fall into a vicious circle of evolution alone.

  Liu Zhixing said that the quasi-zenith system is not globally oriented, and only receivers that can be used in and around Japan cannot guarantee the market scale. Although the field of autonomous driving is one of the application hotspots of high-precision positioning, due to the positioning time and the delay of satellite channel transmission, it can only be used as an auxiliary of other sensors at this stage, and the Japanese business community has not responded very enthusiastically. However, looking to the future, in the fourth stage of autonomous driving, that is, the driving stage dominated by artificial intelligence, the absolute position of centimeter-level accuracy is very necessary. Assuming that the mass production price of L6 corresponding to high-precision chips can reach less than 1,000 yen by then, which is better than the relative positioning sensors such as cameras and LIDAR that are currently relied on for autonomous driving, then the quasi-zenith system may have some competitiveness.

  Beidou is a complete global satellite navigation system

  Liu Zhixing concluded by saying that China’s Beidou satellite navigation system is starting global construction, and the construction of the enhancement system is also underway. In terms of space-based enhancement, recently, at the fourth meeting of the ICAO Navigation System Expert Group, the Beidou Satellite-based Augmentation System (BDSBAS) was officially awarded the SBAS system supplier ID and system time ID. BDSBAS became the sixth satellite-based augmentation satellite navigation system in the world, providing sub-meter-level services for aviation applications. In addition, Hezhong Sytron has been developing the centimeter-level Beidou satellite-based augmentation system since 2013. We can collectively expect "Chinese precision".

Huawei "pure blood" Hongmeng accelerates entry, universities and enterprises target new trends in ecological development

  Financial Union News Agency, January 5 (Reporter Tang Zhixiao)Recently, Yu Chengdong, CEO of Huawei end point BG and chairperson of smart car solutions BU, proposed in the 2024 New Year’s letter to open a new decade of Huawei end point future development.

  He specifically mentioned that to build a strong Hongmeng ecosystem in the future, 2024 is a crucial year for the development of native Hongmeng applications, and will accelerate the development of various Hongmeng native applications.

  It is reported that on January 18, Huawei will hold an important event of Hongmeng, which will reveal the new chapter of Hongmeng ecology and HarmonyOS NEXT.

  According to Huawei’s public information at the press conference, Hongmeng native application ecological construction has been fully launched, and HarmonyOS NEXT will remove the traditional Linux kernel and AOSP code, and will no longer be compatible with Android applications.

  At present, a number of domestic enterprises have started the research and development of Hongmeng applications, many of whichApps under big companies such as Meituan.

  In addition, Huawei chose to cooperate with universities to launch OpenHarmony-related courses; some companies aimed at this trend and launched Hongmeng ecological development courses. Some industry developers said that now Hongmeng end point has reached 700 million, it is hard to imagine that developers will ignore such a huge market.

  The ecological construction of "Pure Blood Hongmeng" is particularly important

  At the Hongmeng Developer Conference, Huawei revealed that the Hongmeng base has more than 100 million lines of code, 20,000 APIs, and 700 million ecological devices. HarmonyOS has undergone four major iterations. For Hongmeng, the most important thing at the moment is to build an independent application ecosystem that is not attached to the application.

  According to incomplete statistics from Starmine, there are,,,,,,,The business scope of 19 other companies covers Hongmeng,And so on Hongmeng ecological related business.

  Among them, Hong Kong-listed company Chinasoft International participated in the development of Hongmeng and HMS, and provided IT services for them. According to the company’s annual report, in the HMS 4.0 stage, the company participated in 17 of Huawei’s 25 HMS planning capabilities, which can be said to be the core supplier of HMS.

  In addition to its own "hematopoietic", what is more critical to the development of Hongmeng’s ecosystem is the adaptation with external third-party enterprises.

  New Consumer Daily reporters have sorted out according to public information, and at least 36 applications have either started or completed the adaptation to Hongmeng’s ecosystem, coveringCatering, finance, information, and other categories, the detailed list is as follows:

  "Huawei is betting that developers will not ignore the huge number of devices in the Hongmeng ecosystem," a mobile end app developer told the New Consumer Daily. "But at the same time, we need to face up to the fact that it will take a lot of energy to redevelop the original Hongmeng app, or to maintain and update the app later. Big companies follow up faster, and small factories and independent developers may move a little slower."

  Aiming at the development gap of Hongmeng, universities and enterprises will fail

  According to public data, 2.2 million HarmonyOs developers have invested in the development of Hongmeng Ecosystem.It is said that the Hongmeng market space is expected to exceed 10 billion yuan.

  A Hongmeng ecological insider said that there is currently a shortage of development talents in Hongmeng, while Android development talents are relatively surplus. The treatment of technical personnel who master Hongmeng is better than that of Android developers, which makes many developers willing to transfer to Hongmeng development.

  In November 2023, Huawei announced the establishment of the OpenHarmony Technology Club with universities, positioning it as a university community organization. At present, 23 985 universities and 46 211 universities across the country are offering or will soon offer Hongmeng-related courses.

  In addition, Huawei has long been involved inThe Industry-University Cooperation and Collaborative Education Project under the guidance of the Ministry of Higher Education only records the Hongmeng-related courses established since 2021, involving more than 150 course projects in more than 100 universities. And the number of projects approved in 2021, 2022, and 2023 is 20, 65, and 68 respectively.

  There are also many companies targeting the Hongmeng ecological developer training market, such asand

  Among them, on the interactive platform, it said that the company is a resident unit of Huawei Developer Alliance Academy, which jointly cultivates Hongmeng ecological talents, and has won honors such as "2023 Huawei Developer Alliance Hongmeng Ecological Talent Development Award".

  The investment platform said: "The company has Hongmeng development courses, and Hongmeng hardware/courses have been added to the two disciplines of" integrated circuit application development (including embedded) "and" HTML & JS + front-end ". The course" HarmonyOS 4.0 Introduction to Development Practical Tutorial "has been launched on Bilibili."

  Previously, it launched the first "Standard Edition of Hongmeng Application Development Learning Roadmap" on the whole network, covering software and hardware development courses, consistent with Huawei’s official website, and joining the actual combat of real business line projects. The training course will start in Beijing in February this year.

  The two companies also stressed that at present, Hongmeng Ecology is still in the development stage, and the impact on the industry and the company needs to be gradually revealed in the future development process.

  Major General Ding, founder of Nail Technology, told the New Consumer Daily reporter that the larger the scale of the equipment carried by the Hongmeng system, the greater its ecological value and the higher the barrier to competition. Hongmeng’s openness and professionalism give it better room for growth.

Hu Ge responded to the remarks of "no filming for five years": not drunk

On August 27, at the movie salon event of "It’s Worth It", Hu Ge joked that the previous post on Weibo "No filming in the next five years" caused a heated debate about the withdrawal of the circle. Hu Ge said that he was not "drunk" as netizens said.

He responded with Wen Shan, the character played in "It’s a Worthy Trip": "In fact, my base color is very different from what everyone sees. I often contradict and tear myself, most of the time I restrain myself, and many times I compromise. This is very similar to the relationship between Wen Shan and Xiao Yin. I talk to myself, but many times the other party will defeat me. Although" It’s a Worthy Trip "has been filmed for a long time, Wen Shan has always influenced me."

Hong Jinbao’s move "Ip Man 2" is old and strong against Donnie Yen


Hong Jinbao, summon all sects to test Ye Wen


Master Hong was in the ring, fighting for the dignity of the nation.

  Ye Weixin directed and starred Donnie Yen in the kung fu masterpiece "Ip Man 2: The Legend of the Grandmaster" will officially open the "Fist and Kick" curtain on April 29. The famous movie star Hung Jinbao joined the second episode to play the grandmaster of Hong Quan, and launched a wonderful duel with Donnie Yen. Although Hung Jinbao is over 60 years old and has a fat figure, all the fighting scenes contributed in the film still go into battle in person, and his skills are not reduced in the past. He is known as "the most agile fat man".

Sequel to face Donnie Yen, staged a super duel

  In the much-anticipated "Ip Man 2: Legend of the Grandmaster", in addition to Donnie Yen and other original stars, all the stars starred in the show, and even invited a generation of star Hong Jinbao to join the show. In the trailer released earlier by the film, the showdown between Donnie Yen and Hong Jinbao was the most eye-catching. Dressed in a gray cloth gown, Ye Wen Minran with a clear face jumped onto the round table and showed a classic speaker action after reporting to his house, which was full of tension. Standing opposite Ye Wen was Hong Zhennan, the head of Hong Quan played by Hong Jinbao. After "Kill the Wolf", Donnie Yen and Hong Jinbao’s on-screen showdown is expected again, and the super PK battle of "Hong Quan and Wing Chun" will also become the most anticipated action point in "Ip Man 2".

There is a reason for being fat and being praised as "the most agile fat man"

  Hung Kam Pao was a "big brother" and "miscellaneous boy" in the Hong Kong film industry in the 1980s. Hung Kam Pao has a wide range of films, including actors, action directors, directors, producers, screenwriters, and dragon and tiger martial artists. He has won the Hong Kong Film Awards for Best Actor and the Asia Pacific Film Festival for Best Actor. Hung Kam Pao’s obesity came from an injury. During a training session, he was hospitalized for breaking his ankle. During this period, his grandfather often sent some snacks to comfort his grandson. As a senior brother, Hung Kam Pao refused to share food with other students. A large amount of high-calorie food and complete lack of activity caused his size to quickly expand, and later he looked like a big fat man, until now. Although Hong Jinbao is over 60 years old, all of them still play in person, their skills are not reduced, and they are also praised as "the most agile fat man" in the crew.

Movie Network ViewpointWhat is it?The success of the first installment of "Ip Man" naturally allowed the audience to extend their expectations to this installment. Kung Fu superstar Donnie Yen considered himself to have "surpassed" in "Ip Man 2", "apprentice" Huang Xiaoming even practiced "Wing Chun" for 3 months, and "Sister-in-law Ip Man" Xiong Dailin also came out with a big belly… Whether "Ip Man 2" can be as successful as the first installment, we will wait and see.

Gross margin is back in double digits, has NIO passed the most dangerous moment?

In the new energy and new forces, NIO is the company with the greatest ups and downs, or even one of them.

In this year’s Hong Kong stock market, NIO is one of the few new energy vehicle companies whose share price has fallen. Since the beginning of the year, NIO’s share price has fallen by more than 24%, the ideal share price has risen by more than 80%, Xiaopeng has risen by more than 61%, and BYD’s shares have risen by more than 12%.

Behind the weakness of NIO’s share price, a very important reason is that in the current era of increasingly fierce competition for new energy vehicles, NIO’s overly expensive approach has added more uncertainty to it.

With the release of the third quarter report, this situation has changed. In the third quarter, NIO delivered 55,400 vehicles, an increase of 135.7% month-on-month, a record high, and gross profit margin increased by 4.8 percentage points month-on-month to 11%, exceeding market expectations (10.2%). NIO, who breathed a sigh of relief, rose nearly 10% two days after the release of the financial report.

More noteworthy than the financial figures is that NIO has finally begun to learn to save money, such as opening the power exchange alliance, abolishing non-core business departments, etc. But the crisis has not completely passed, and as new energy vehicles roll into the high-end car market, NIO will also face a new test.

This paper holds the following views:

1.NIO’s third-quarter results exceeded expectations, but it remains under pressure for the long term.In the third quarter, NIO deliveries and gross profit margins achieved rapid growth. But this largely relied on the untying of power exchange services and car purchases. Those who were unwilling to use power exchange services paid less, which stimulated sales. In July and August, NIO’s monthly sales were around 20,000 vehicles. But by September and October, NIO’s monthly sales had fallen back to about 16,000 vehicles.

2.NIO began to learn to save money.NIO eliminated redundant business, driving the proportion of sales and administrative expenses down 13.6 percentage points month-on-month. At the same time, NIO is also making active strategic adjustments and measures, such as opening up power exchange services to enhance scale effect and reducing vehicle manufacturing costs independently.

3.NIO is taking a big test in the high-end car market.All parties in the industry are collectively sprinting to the high-end car market. At the beginning of next year, Ideal and Xiaopeng will have new models priced at 300,000 yuan. And before the second half of next year, NIO will not have new models on the market. In the case of already declining sales of existing models, NIO’s competitive pressure will increase unprecedented.

01 Gross margin back in double digits

Gross margin has always been the most concerned indicator of NIO’s financial reports. Affected by factors such as falling sales volume and industry price wars. NIO’s business gross margin has stayed in single digits for three consecutive quarters. In the third quarter, NIO reversed this trend, and the automotive gross margin increased by 4.8 percentage points month-on-month to 11%, exceeding market expectations (10.2%).

NIO’s gross margin returned to double digits after three quarters, not only due to the decline in supply chain costs, but also due to the return of NIO’s sales volume to high growth.

The price of battery-grade lithium carbonate fell from 307,500 yuan/ton in July to 171,000 yuan/ton on November 1. Considering that the cost of batteries in pure electric models accounts for about 40%, the decline in battery prices will naturally bring about a decrease in car costs. NIO also mentioned in the third quarterly report that the company’s battery unit cost decreased in the third quarter.

At the same time, NIO sales also returned to high growth in the third quarter. In the third quarter, NIO delivered 55,400 vehicles, an increase of 135.7% month-on-month, and the delivery volume reached a record high. The dilution of amortized costs caused by the significant increase in car sales made NIO bicycle costs 7,000 yuan lower than in the previous quarter.

Among them, in the car sales structure, the ES6 with relatively high pricing has boosted sales by changing the model. Its sales share has increased from 25% in the last quarter to 50% in the third quarter, so that the average price of bicycle sales has increased to 314,000, an increase of 8,600 yuan from the previous quarter. The cost of each car has decreased by 7,000 compared with the previous quarter, but the price has increased by 8,600, so that the gross profit of each car sold by NIO in the third quarter is 35,000 yuan, which is 16,000 higher than the previous quarter.

Although the increase in sales volume and the increase in the proportion of high-priced ES6 have driven the improvement of the company’s gross profit margin. But in the long run, it is difficult to maintain the high growth of NIO sales. The reason is that the increase in sales in the third quarter was affected by the untying of power replacement and car buying services, and the disguised price reduction promoted the release of sales. In July and August, NIO’s monthly sales were around 20,000, but in September and October, the monthly sales volume had dropped to about 16,000.

Although the high growth brought about by the unbundling of power exchange services is a short-term event, changes in business strategy are having a profound impact on NIO’s profitability.

02 NIO starts to learn to save money

At the NIO Science and Technology Innovation Day two months ago, Li Bin said this: "Yesterday, He Xiaopeng asked a media person to tell me not to invest so much money, thank you, but NIO will continue to invest in the long-term."

Li Bin’s words were also in line with the outside world’s perception of NIO. Compared with other new forces, NIO would "burn money" more. But in the end, the situation was stronger than people.

In the third quarter, NIO’s sales and administrative expenses fell by 13.6 percentage points quarter-on-quarter. The decrease in expense ratio is due to NIO’s elimination of redundant business. "NIO will carry out adjustments involving organizational and resource investment directions, including reducing the redundant personnel and institutional settings by about 10%," Li Bin said in an internal letter in November. At the same time, NIO will also make adjustments to projects that have not been profitable for three years or have not contributed to the improvement of gross profit. Dolphin Investment Research forecasts that after the layoffs, it is expected to save NIO 10-1.50 billion per year.

Not only shrinking the business, NIO also adjusted its strategy. At the end of November, NIO successively cooperated with two major automakers, Changan and Geely, on the power exchange business. For a long time, due to the huge investment and the harsh requirements of the break-even point, the power exchange service has been a drag bottle for NIO’s profits. In the third quarter, the gross loss rate of the service business including the power exchange business reached -24%. That is to say, the gross profit earned by selling cars 350 million, all posted to the losses of other business 390 million.

After cooperating with car companies, the partners can not only share the investment pressure, but also increase the number of power exchange services per day at the power exchange station, improving the scale effect. Next, Li Bin also said that the possibility of independent financing of the power exchange business cannot be ruled out.

After rationally allocating non-core businesses, NIO also has more resources in the main automotive industry. Recently, it was reported that NIO has obtained independent production qualifications. If the news is true, it means that NIO’s seven-year OEM route has come to an end and it has become the last car company in the new force to obtain independent car manufacturing qualifications.

Not surprisingly, after obtaining the production qualification, it will be beneficial to the efficiency of NIO’s business. According to Li Bin, after purchasing the Jianghuai production line, the cost of independent production will decrease by 10%, and the gross profit margin of automobiles will continue to increase, reaching 15% in the fourth quarter.

Although NIO itself has started to learn to save money and is getting better and better, it is also facing new industry challenges.

03 The industry collectively sprints towards high-end cars.NIO faces new pressure

In NIO’s plan, the goal is to be China’s BBA and dominate the domestic high-end pure electric market for a long time. From the current point of view, this goal is progressing smoothly. From January to May this year, NIO’s market share of high-end pure electric vehicles with an average transaction price of more than 300,000 yuan reached 55.8%.

Although the performance is good, it may be difficult for NIO to continue to increase its share. Due to the different operating habits and aesthetic styles of consumers, cars are highly differentiated products. Toyota, the world’s largest automaker, has a market share of only 11%.

From the current point of view, NIO’s share in the high-end pure electric market has declined. In October, NIO’s share in the high-end pure electric car market above 300,000 yuan was 45.6%, a significant decrease from the first five months of this year. Another signal of bottleneck in the penetration rate of NIO’s high-end cars is that NIO will launch two sub-brands, Alps and Firefly, focusing on the market below 300,000 yuan.

At the same time, the new energy automobile industry has also begun to sprint to the high end collectively. According to later reports, next year, Ideal, Huawei, JK and other brands will launch products on the market with prices of 300,000 yuan and above.

In January next year, Xiaopeng MPV new car – Xiaopeng X9 with a pre-sale price of 388,000 began to be delivered to users. In the third quarter of this year, Xiaopeng bicycles cost an average of 196,000 yuan. In late February next year, the ideal first pure electric car priced close to the ideal Mega of 600,000 will also be delivered to users.

Interestingly, the timing of competing for high-end cars is precisely the empty window period for NIO products. NIO will not have new cars on sale until the second half of next year, and can only rely on the current eight cars on the NT 2 platform to sell. And two of the so-called main models – ET 5 and the new ES 6 – have obvious sales weakness. The fourth quarter sales guidance given by NIO 4.7-4 9,000, and it also shows a month-on-month downward trend. Before the second half of next year, NIO will only rely on stock car sales to deal with new high-end cars from brands such as Ideal and Xiaopeng. This means that the competitive pressure of NIO will increase unprecedented.

Although the unit price of NIO customers is higher, due to the crude development of NIO in the past, the gross profit margin of NIO is only 11%, coupled with the service business that has not been able to achieve profit returns, the overall gross profit margin of NIO is only 8%, which lags behind the gross profit margin of most mainstream new energy vehicle companies. Once NIO’s high-end market position is shaken, NIO will gradually lose its room to move around in the industry.

This also means that the danger of NIO is still not over. In the ever-fierce competition of high-end cars in 2024, NIO will enter a new round of life and death test.

Geely automobile is on the rise again, and young people can afford it.

Appearance is the primary reason why I chose this car. The family-style design style has been upgraded on the basis of the past, and Geely’s personality is more distinct. The intricate and orderly line grille is finely connected with the headlights, which effectively strengthens the horizontal visual tension, and the side skirt is finely handled, which contributes to the overall beauty of Geely Jiaji. Compared with the appearance, the gap is obvious. I am more satisfied with the appearance and interior of Geely Jiaji. The design style of the center console and buttons is fashionable and forward-flowing, which makes people overjoyed. Soft materials are everywhere they can touch, and the details are properly handled. In addition, metal keys and painted decorative boards are used to further improve the layering. Compared with the interior of Toyota Highlander, Geely Jiaji’s simplicity, generosity and sense of grade appeal to me more. The seat enjoys a strong wrapping, and passengers will not feel obviously tilted when turning. To be honest, compared with Toyota Highlander, Geely Jiaji’s interior looks much higher.

In the interior, the new Jiaji adopts Geely’s brand-new family-style design language, and the layout of the whole car tends to be simple at home. The 10.25-inch high-definition central control screen, cool LCD dashboard and damping physical buttons are all very scientific and technological, and the three styles are not absent. The overall interior design is very in line with the aesthetic needs of young people.

The length, width and height are 4826×1909×1695mm respectively, and the wheelbase has reached 2805 mm. In the same class, Jiaji’s wheelbase ranks fifth. This size exceeds most models in its class. The actual interior space performance is also very good. From the actual ride experience, the front and rear rows are relatively spacious. Jiaji Jiaji L 1.5T skylights provide a wider view, which can create a better visual environment and good sensitivity for the rear passengers and increase the light intake for the whole vehicle. Spatial performance is limited by vehicle positioning, and the performance is acceptable, and the flatness is no problem, but the total space is average.

Jiaji Jiaji L 1.5T distinguished model adopts 1.5 engine, with maximum horsepower of 181 and peak torque of 290, which is matched with wet dual clutch (DCT) gearbox. It will definitely bring unforgettable control charm. Ranked 7 th among 80,000-120,000 models.

Farewell to mobile map Autonavi officially released AMAP AUTO

    [XCAR technology, original]

    Autonavi released the Autonavi map car version (AMAP AUTO) on April 7. This car-machine version of navigation simply takes the navigation originally displayed on the mobile phone and moves it to the car screen, and then adds some new elements: such as a cloud and multiple screens, and a mobile phone car-machine interconnection function to solve the problem of walking navigation after getting off the car. At first glance, this product seems to only make it convenient for users to use navigation while driving, but while making it convenient for users, Autonavi also solves an industry pain point: the front-mounted car navigation is not easy to use.

    It has become an indisputable fact that the front-mounted car navigation is not easy to use. There are many reasons for this phenomenon, but the final result is only one: even if the car navigation is installed, many people will still use the navigation products on their mobile phones. Using mobile phone navigation during driving is very dangerous, so it is often necessary for the co-pilot’s partner to temporarily play the role of "navigator". If the car navigation can be used better, the happiness index of travel will be improved.

    Compared to the mobile version of navigation, the biggest innovation on the Autonavi map car version is the addition of the function of one cloud multi-screen and mobile phone car-machine interconnection. The function of one cloud multi-screen is easier to understand. In addition to the main screen of the central control that can display navigation information, the screen belonging to the rear passengers in the car can also display navigation information synchronously.

    The function of mobile phone car-machine interconnection is more practical. When the destination we navigate is still some distance away from the parking location and we need to continue to use the navigation after getting off the bus, the navigation on the car can directly transfer the destination information to the mobile phone, allowing the mobile phone to continue to navigate for the user without entering the destination again.

    One of the reasons why I would rather hold my phone and watch the navigation by myself when driving than use the original navigation in the car is because the mobile navigation can plan the smoothest route according to real-time road conditions. If the navigation is moved to the car, can it still avoid congested road sections?

    Of course. Autonavi connects online through the Wi-Fi hotspot provided by the mobile phone, and completes functions such as map updates in this way. But this method also has drawbacks: if the vehicle does not have the function of connecting to the network, the mobile phone needs to keep the Wi-Fi hotspot on all the time to provide real-time road condition information to the car, but this will consume a lot of power. So for those car owners who can use SIM to connect to the Internet, the Autonavi map version of the car will be more practical.

    Autonavi is working with two independent manufacturers, Geely and Changan, to install the Autonavi map car version directly in front of the products of these two brands. It also supports the use of models of Volkswagen,,,, and many other brands. It will cooperate with more brands in the future. Dr. Li Yusheng, chief engineer of the General Engineering Research Institute, said that in addition to the Autonavi map car version installed in the front of Changan products as a navigation, it will also consider cooperating with Autonavi in the autonomous driving project of Changan.

    editorial reviewThe mobile phone navigation has been moved to the large screen of the central control. Autonavi does make it convenient for users to use navigation while driving. But if the model cannot be connected to the Internet through the SIM card, it still feels a little inconvenient to use the mobile phone hotspot to achieve interconnection. In addition to cooperating with Changan and Geely on front-loading navigation, Autonavi is also preparing to cooperate with Changan’s autonomous driving project. Obviously, Autonavi is going to play a big game.

Drawing the "Belt and Road Initiative" aviation and trade map to "navigate" for promoting economic and trade cooperation

  Xinhua News Agency, Shanghai, September 3 Title: Drawing the "Belt and Road Initiative" Air and Trade Map to "Navigate" for Promoting Economic and Trade Cooperation

  Xinhua News Agency reporter Jia Yuankun

  The "Belt and Road Initiative" trade volume index, the "Belt and Road Initiative" freight volume index, and the "Maritime Silk Road" freight rate index, the three data streams are combined into a "Belt and Road Initiative" air trade map, which is the "Belt and Road Initiative" air trade index officially released by the Shanghai Shipping Exchange on July 11, 2017.

  Like the "chart" used by ocean-going freighters, the "Belt and Road Initiative" air trade index has not only become a "barometer" that comprehensively and objectively reflects the economic and trade exchanges between countries and regions related to the "Belt and Road Initiative", but also enhances market transparency through information services, providing an important reference for promoting economic and trade cooperation.

  Three data streams plot the "barometer" of air trade

  The "Belt and Road Initiative" initiative brings new opportunities for trade and economic cooperation between relevant countries and regions. Where are the cooperation opportunities? How much flow of each product and where are the main markets? When information is not shared and demand is not communicated, the market is often in a wait-and-see state, and all parties need clear market information as a reference for decision-making.

  In line with the original intention of providing information services for the market and enhancing market transparency, since 2015, the Shanghai Shipping Exchange has started to develop the "Belt and Road Initiative" air trade index.

  "A single freight index cannot fully reflect the trade trends of countries and regions under the Belt and Road Initiative, and it is difficult to meet market demand. On the basis of developing the traditional strong freight index, the Shanghai Shipping Exchange has also explored the two dimensions of trade volume and trade volume. The purpose is to improve market transparency, truly reflect market supply and demand, and promote the long-term and healthy development of the market." Zhang Yi, president of the Shanghai Shipping Exchange, said.

  Due to the different types and values of goods, the relationship between trade volume and trade volume is not linear. For example, clothing, luggage and other trade volume is large, but the trade volume is relatively low, while the same volume of machinery and electronic products, the trade volume is much higher. The trade volume, trade volume data and the freight data of the corresponding route can comprehensively and objectively reflect the market active level and demand trend.

  The "Belt and Road Initiative" shipping index information is comprehensive, covering 65 countries along the "Belt and Road Initiative", distributed in North Asia, Central Asia, South East Asia, West Asia, North Africa, Europe and Oceania and other regions. The index is not limited to containers, but also includes bulk materials such as coal, railway stones, and crude oil. The mode of transportation is not limited to sea freight, but also includes rail transportation.

  To serve as a "barometer" of market trends, the authenticity and accuracy of information are essential. The "Belt and Road Initiative" air trade index data is widely collected by making full use of the membership advantages of the Shanghai Shipping Exchange. At present, the members of the Shanghai Shipping Exchange include about 130 well-known domestic and foreign shipowners, cargo owners and brokers from various transportation segments, and have high international recognition.

  The research and development of the "Belt and Road Initiative" air trade index is not only to serve shipping companies to open up routes and cargo owners to open up markets, but also to provide an information platform to enable enterprises in countries and regions along the route to communicate with each other, increase exchanges and promote trade.

  Since its official release on July 11, 2017, it has been published by the Shanghai Shipping Exchange on the China "Belt and Road Initiative" website every month. The "Belt and Road Initiative" air trade index consists of both monetary indicators, which reflect changes in trade volume and overall scale, quantitative indicators, which reflect the growth of specific trade flows, and price indicators, which reflect changes in market supply and demand and competition.

  "As a third-party platform, the freight index published by the Shanghai Airlines Exchange is highly influential, fair and just, and has been widely recognized by cargo owners and agents," said the shipping companies interviewed.

  "Chinese companies need to understand market information to explore overseas markets, and foreign companies need scientific services to enter the Chinese market," Zhang said. "Through the air trade index platform, companies can grasp the trade demand and trend of the market, the import volume and export volume of a certain product, and which regions mainly flow to China. This data information is an important basis for foreign companies to understand the supply and demand of the Chinese market."

  The "Maritime Silk Road" comprehensive index covers the freight rates of major cargo types, major routes, and major ship types of shipping. Its application is not only reflected in investment decisions, but also in risk avoidance, such as spot index linking and freight forward transactions.

  "The freight index is a bellwether that reflects the market level. At present, 45% of coal shipments along China’s coast are subject to index-related agreements to varying degrees, laying a good foundation for the promotion and application of the Belt and Road Initiative’s air trade index," said Liu Yue, manager of the information department of the Shanghai Shipping Exchange.

  Launch a shipping service brand and build an international cooperation platform

  Air trade information is a service product. To further promote its application and win the trust of enterprises in countries and regions along the route, it is necessary to use its comprehensiveness and scientificity to launch this shipping service brand. "The application of the Belt and Road Initiative air trade index has just started, and it is still necessary to continuously optimize and expand the connotation of the index. We also expect other national institutions to participate in the compilation and expand the application scope of the index." Zhang Page said.

  In addition to shipping and railways, in terms of transportation methods, the "Belt and Road Initiative" air trade index will include road and air transportation in the index system in the future; in terms of route layout, transportation routes between "Belt and Road Initiative" countries and regions will also be developed.

  At the same time, the Shanghai Shipping Exchange will also accelerate the application of the "Belt and Road Initiative" shipping index in the economic and trade fields of countries and regions related to the "Belt and Road Initiative", encourage traders and shippers in various countries to use the "Belt and Road Initiative" shipping index for index linking when signing trade and transportation contracts, and make the index a hedging tool for managing market volatility risk.

  The establishment of the information platform relies on a wider range of information sharing to create a data aggregation effect. In the process of promoting the application of the index, the Shanghai Airlines Exchange has simultaneously recruited other national institutions to participate in the compilation of the "Belt and Road Initiative" trade and freight index between countries and regions.

  "Behind the realization of policy communication, facilities connectivity, unimpeded trade, financial integration and people-to-people connectivity, the flow of data and information is covered. Relying on the index platform and related information, jointly developing with countries and regions along the route, and creating the’Belt and Road Initiative ‘trade and freight big data platform will further upgrade data and information services," Zhang Page said.

China Evergrande Hong Kong liquidation hearing further postponed

On December 4, according to the Hong Kong Economic Times, the hearing of China Evergrande’s liquidation petition originally scheduled for December 4 was postponed to January 29 next year. The group said that it would take time to discuss the restructuring plan, so it requested a five-week postponement, and the remaining creditors did not object to the postponement of the application. The debt scale of the housing company is as high as 2 trillion yuan.

One of the key factors is the progress of Evergrande’s overseas workout. In September, the group said it had to reassess its overseas workout plan and said it could not meet China’s requirements to issue new bonds. Previously, it was reported that in the revised workout plan, the group offered 17.8% of the group’s shares in addition to the offer of 30% shares in two Hong Kong subsidiaries of Evergrande Property and Evergrande Automobile to creditors.

This is the sixth extension of the liquidation hearing of China Evergrande Hong Kong. In June last year, creditors filed a liquidation petition against Evergrande in the High Court of the Hong Kong Special Administrative Region of China. At that time, the hearing was scheduled for August 31, 2022. Subsequent to that, the hearing has been postponed five times. On October 30 this year, the group announced that the Hong Kong High Court had postponed the liquidation hearing to December 4.

After a long road to restructuring, Evergrande has yet to see a clear turnaround. There are reports that if the company submits relevant plans to meet the set standards, the court is "likely" to issue a winding-up order at the next hearing.
