"Fight for the value of Chinese cars" has never been a slogan. Geely China Star is writing the story behind this sentence with its high sales, high value and high premium, and leading Chinese brands to break through.

Data show that the total sales of China Star currently exceed 200,000 units, with monthly sales of 20,000 units, quickly detonating the Chinese auto market, becoming a phenomenon, and successfully entering the "price hinterland" of joint venture vehicles. On November 19, China Star’s flagship SUV Xingyue L ushered in evolution, and launched the Xingyue L Thor Hi · X gasoline-electric hybrid version at the Guangzhou Auto Show, breaking the inherent definition of non-traditional fuel vehicles or new energy vehicles in the past, and becoming "a higher organism in the automotive industry, a new species that continues to evolve". At the same time, Xingyue L also ushered in the first OTA upgrade of the whole vehicle, launched the "Xingyue L Star Enjoy Official Co-creation Plan", and continuously brought users a commonly used and new product experience.

Since its debut, China Star has attracted a lot of attention for breaking through the boundaries of independent and joint ventures and breaking through the barriers of technical constraints. Today, China Star not only rivals the joint venture brands, but also shows a better position in the value competition and becomes the mainstream choice of high-value.

Evolution: A number of leaders, bringing new species of gasoline-electric hybrids

China Star is a CMA high-end series created by Geely into the era of Geely 4.0 comprehensive architecture car manufacturing. It is composed of Xingyue S, Xingrui, and Xingyue L. It integrates the latest technological achievements of Geely Automobile and breaks the barriers defined by joint venture brands in the past. Among them, China Star’s flagship SUV Xingyue L not only redefines the new standard of SUV, but also has epoch-making significance.

In fact, when Xingyue L was listed, Li Shufu, chairperson of Geely Holding Group, once said, "Xingyue L not only inherits the advantages of traditional cars, but also absorbs the bright spots of new energy vehicles, opening up a new path for the transformation and upgrading of traditional cars." Now the launch of the Raytheon Hi · X gasoline-electric hybrid version once again confirms the characteristics of Xingyue L taking into account the advantages of fuel vehicles and new energy vehicles.

The evolved Xingyue L Raytheon Hi · X gasoline-electric hybrid version is Geely’s first model launched after entering the "Power 4.0 Era". It is based on the just-released "Raytheon Zhiqing Hi · X" world-class modular intelligent hybrid platform. It has far superior strength in performance, energy saving and intelligence than its Japanese hybrid competitors.

Specifically, the Xingyue L Raytheon Hi · X oil-electric hybrid version is equipped with a hybrid core drive system composed of a three-speed variable DHT Pro drive motor and a DHE15 hybrid special engine, enabling the geometric expansion of the intelligent driving mode and covering more working conditions.

Among them, the "China Heart" top ten engine DHE15 hybrid special engine, thermal efficiency has reached an unprecedented 43.32%, the coverage rate of high efficiency area is close to 50%, the maximum power is 110kW, the maximum torque is 225N · m, and the liter power and liter torque are veritable best in the same class. The three-speed electric drive transmission DHT Pro is the intelligent energy control center of this car. In the axial size of only 354mm, it is highly integrated with a generator motor and a drive motor, two motor controllers and a three-speed ratio variable speed and torsion mechanism. Under the combined action of the DHE15 engine, the average fuel consumption of 100 kilometers is as low as 4.3L, and the maximum cruising range of full fuel is 1300 kilometers, bringing the strongest power and lowest fuel consumption performance among HEV models in the same class.

At the same time, the Xingyue L Raytheon Smart Engine Hi · X gasoline-electric hybrid version has a full-speed domain parallel function, which can enter the parallel mode at a speed of more than 20km per hour to achieve ejection start, which is much lower than the parallel speed of at least 70km for Japanese hybrid cars, and the system efficiency is increased by 20%.

As a milestone product in the hybrid field, Xingyue L Raytheon Smart Engine Hi · X Hybrid Edition not only pioneered the era of multi-mode transmission of hybrid electric drive, but also adopted the intelligent electronic and electrical architecture GEEA 2.0 to realize the joint control of the power domain and other domains of the vehicle. The system can identify the driver’s driving habits and road congestion, realize driving mode adaptation, self-learning and self-adjustment, and enable 20 intelligent working modes to switch without feeling.

Upgrade: Often used and always new, bringing an experience that exceeds expectations

While Xingyue L has expanded its product lineup to the field of gasoline-electric hybrids, opening up a new path for the transformation and upgrading of traditional automobiles, Xingyue L has not forgotten to speed up its own iteration in intelligent ecology. At this auto show, Geely released the Geely Galaxy OS vehicle function OTA carried by Xingyue L, which brought 49 product upgrades worth 2,750 yuan, continuing to bring users a comprehensive vehicle intelligent ecological experience. It is reported that users who place an order before December 31, 2021 can open the upgrade for free.

In fact, this is the second upgrade of Xingyue L, which has been on the market for only four months. In August this year, Xingyue L has brought a Geely Galaxy OSV1.1 version upgrade to users, bringing 17 new smart experiences to users in four aspects: interaction, vision, application and intelligent control. The officially released OTA function of the whole vehicle adds Huawei Hicar function, which allows mobile phones to cast screens, such as map projection, game playing, etc., as well as more comfortable and convenient new functions.

As the world’s first mass-produced global FOTA fuel SUV, in the future, Xingyue L will push FOTA upgrades every quarter, which will bring product experiences that exceed expectations in intelligent driving, power performance, body control, and digital cockpit interaction. More importantly, OTA upgrades will not be limited to application ecological expansion and experience optimization in the traditional sense, but also put the upgrade of vehicle performance on the agenda. In the future, Geely will continue to keep the Xingyue L’s usual and new through iterations of the underlying design, power performance, and Geely Galaxy OS speed upgrades.

It is worth mentioning that these upgrades of China Star will be co-created with users. In Geely’s view, "products are ships, marketing is sails, and users are water", and user co-creation is the source of China Star’s living water. As early as May this year, Geely announced the user brand "we", becoming the first car manufacturer in the world to release a user brand, narrowing the distance with users.

At this year’s Guangzhou Auto Show, Geely once again promoted the implementation of the "Co-Creation Plan", opened the "Xingyue L Star Enjoy Official Co-Creation Plan", issued a total of 10 million gigabytes to encourage co-creation, invited users to propose the evolution direction of Galaxy OS according to their own preferences and thinking, and put forward their own plans for digital smart cars. Users who contribute will get the permission of Xingyue L permanent free FOTA.

From the world’s first recruitment of Star Enjoy officials, to the listing of 28,000 + Star Enjoy officials to witness together, and then to this OTA upgrade, the launch of the "Star Enjoy L Star Enjoy Officer Co-creation Plan", the continuous maintenance of the evolution ability of Geely Galaxy OS, and the creation of user communication activities IP – CMA Day, CMA Hour, CMA Summer, CMA Life, etc., user co-creation has long been engraved in Xingyue L, and in the genes of China Star, in the "open, co-creation, exploration, happy" user ecosystem, continue to bring users new experiences that exceed expectations.

Break the circle: face to face, enter the "price hinterland" of the joint venture car

The evolution and upgrade of Xingyue L is in fact a microcosm of China Star’s upward breakthrough. China Star’s total sales exceeded 200,000 units and monthly sales exceeded 20,000, becoming the "China Star phenomenon" that appeared again in Geely after the "Boyue phenomenon". It opened up a new track for Chinese brands to rise, and also showed people the courage, determination, sincerity and strength of China Star to fight for the "value of Chinese cars".

When China Star was officially released, Geely made it clear that it would fight for the "value of Chinese cars" and aimed the battlefield at the mainstream joint venture market. Now, China Star has successfully entered the "price hinterland" of the joint venture brand, breaking the boundary between joint venture and autonomy, and truly facing the "high value" and joint venture brand head-on.

Behind this evaluation, there is full user support and data support. Xingrui has accumulated more than 120,000 units in the 12 months of listing, with high-end models accounting for 66% of sales. The average transaction price exceeds 130,000-140,000 yuan, breaking the "ceiling" of the main sales price of Chinese brand sedans 100,000 yuan, becoming the only Chinese brand sedan with a monthly average of more than 10,000 yuan in the 110,000-150,000 level sedan market. Xingyue L has been listed for more than three months. Sales volume is 30,355 units. At present, the total order has exceeded 75,000 units. Sales of high-end models account for more than 62%. The average transaction price of the whole series is as high as 170,500 yuan. It has become the only Chinese brand model with a monthly average of more than 10,000 in the 120,000-180,000 level five-seat SUV market.

Another set of data more intuitively reflects the impact of China Star on the joint venture market. "Now 60% of the replacement users of the’Star series’ are from joint venture brand users, which is the broken circle of China Star," said Lin Jie, senior vice-president of Geely Automobile Group.

Relying on Geely’s technological advantages in the 4.0 era and global high-quality resources, China Star continues to break through the value ceiling to lead the global architecture car-making era, the global hybrid new energy era, and the global 5G intelligent travel era.

Regarding the future, Fan Junyi, executive deputy general manager of Geely Automobile Sales Company, is full of confidence. The goal is that the China Star series will account for 30% of Geely’s total sales in 2022. In fact, "China Star is the first choice for Chinese car buyers, which has become the consensus of Chinese users in the new era. In the era of new technology, China Star will represent Chinese manufacturing to participate in global competition and shine on China’s technological strength.

　　On October 24th, Uber invited some customers to participate in the closed beta before going online to experience the new "Uber Uber China" app in depth.

　　Uber insiders have previously revealed that this new app will combine the most popular features of Uber and Didi in one. The first version is the most concise version, and it will continue to be upgraded and optimized in the next few months. Let’s try it out first and see what changes this "new Uber" has made.

　　Before talking about changes, let’s talk about what hasn’t changed:

　　First, the minimalist aesthetic. Everyone’s favorite Uber, clean interface remains the same.

　　After the download and installation are completed, the icon still maintains the style of the original version, the only difference is that the word "new" is added in the lower right corner of Icon, which is different from the old version in a simple and clear way.

　　From the surface, the logo and naming of the original app are the same as before, and the login process has not changed.

　　There will be a seamless transition between the old and new apps. Uber’s existing users in China will be able to continue to log in with their original accounts, and most users will no longer need to re-enter their passwords and bind payment methods when using the new app.

　　The taxi process has not changed. Get off the bus and pay or just leave. The payment method is secret-free payment…

　　Everything is the same. So where is this new Uber app "new"?

　　A closer comparison of the old and new versions of Uber will reveal that some of the more obvious changes are that the Uber app has added many functions on the Didi app, such as WeChat docking, online real-time customer service, etc., but also "missing" some functions and modules in the old version of the app, such as globalization function.

　　The first point is faster. The more obvious user-related change is that the download package size is the previous (iOS) and (Android).

　　The overall feeling after opening the new app is that it feels a lot faster. The new version loads extremely fast, and the jumping between pages is smoother than before.

　　This feeling is demonstrated after querying the properties.

　　The relevant attributes show that the installation file of the original version of the Uber App has reached 91MB, while the newly downloaded Uber App is only 22.6MB in size. The Android download package has also changed from 21.2MB to 10.6MB, and the installation package size is only 1/4 of the original download package size.

　　It is speculated that this can be achieved for a variety of reasons: because the Uber interface and product line are relatively simple, without the need for so many modules, and the technology and methods of the product team are different from those in the past.

　　It is revealed that in addition to the smaller download package, the new app’s memory, traffic, and power will be more economical in the past, and the page jump speed will also be faster.

　　Second: Add real-time online manual customer service

　　The help page is connected to real-time online manual customer service.

　　As a veteran user of Uber, in the past, although seeking complaints and suggestions could be reported through the message in the app, although this method has become very popular abroad, Chinese consumers are not used to it. Didi customer service has telephone customer service, so it can be expected that the merged Uber will also provide telephone customer service.

　　The new version adds "vehicle color information," a feature that is also available on Didi’s app but not previously available at Uber, and can help taxi riders see vehicles at first glance.

　　Fourth, it is easier to communicate with the driver. To communicate with the driver, you can leave a message in the app, no longer just rely on phone calls.

　　In the past, Uber was used to connect with drivers, and by "contacting the driver", the system would dial the driver’s phone number. In some cities of Uber, some cities have previously been able to "talk" with drivers by leaving messages in the app.

　　The fifth change is that after a year and a half, WeChat has finally developed the new Uber. You can use WeChat to share routes and recommend friends for rides

　　The safety of online car-hailing has always been everyone’s top concern. The "share real-time itinerary" function was first launched by Uber. Previously, on the Uber app, real-time online itinerary webpages could be shared by text message, and family and friends could know the real-time location of passengers by clicking on the webpage.

　　The new app still maintains this function, but WeChat and QQ channels have been added to the sharing channel, allowing users to share their real-time routes in more ways.

　　WeChat’s overnight forceful entry into the Uber app is unexpected, but it seems reasonable. In addition to sharing trips, you can also use WeChat and QQ to recommend ride discounts to others, which is also a function that Uber’s old app does not have.

　　Sixth, focus. The new version currently only retains two product lines, "People’s Uber +" and "Preferred Cars", focusing on the sharing economy and compliant vehicles

　　The interface, the map, the familiar red car, the estimated time to prompt the estimated arrival of the nearest vehicle, and the "Click to use the car" button all maintained the original style, while the function keys below were streamlined to the greatest extent, retaining only "People’s Uber +". (Including carpooling) and "Preferred car" two main businesses.

　　In the past, Uber has had different types and numbers of product lines in various cities (People’s Uber, Preferred Car, Privilege Car, Cross-City Car, 7-Seater Car, etc.). It is known that after the launch of the new app, most cities across the country have only temporarily retained the People’s Uber + and Preferred Car product lines, and other product lines may be added in the future.

　　The most significant change is that foreign users may be affected.

　　Uber’s new app is "missing" some features and modules from the old version of the app, such as temporarily unable to use overseas, missing the English version of the interface and temporarily unable to bind international credit cards. According to internal sources, these features are expected to be gradually improved in future upgrades.

　　In the past Mid-Autumn Festival National Day holiday, the reporter of the Yangzi Evening News Ziniu news cycled more than 500 kilometers and delivered 173 orders of takeaway, realizing the hardships of the takeaway brother. The reporter braved the rain to deliver milk tea to the construction engineering company next to Niushou Mountain, and also went to Sanqiao Wetland Park to deliver camping ingredients for foreign tourists on the full moon night of the Mid-Autumn Festival, and crossed the Jiajiang River many times to deliver supper to the citizens. The reporter observed that the number of orders sent to construction sites, parks, and subway stations has increased significantly. These orders are far away, off-road, and difficult to deliver. When the reporter finished work late at night, he was also cared for by restaurant owners and roadside stall owners many times, which made the reporter feel warm and warm.

　　Ziniu News reporter, Yan Chunxu

　　1. More than 10 takeaways were sent to the construction site, and the truck driver ate in the car

　　At 6:21 p.m. on September 29, the reporter received an order from the platform to pick up the food from the braised chicken and rice (Gemdale Central Store) and deliver it to a tram limited company near Exit 8 of Yuzui Subway Station, about 4.2 kilometers apart. When the reporter finished picking up the food and prepared for delivery, he saw an order for Exit 8 of Yuzui Subway Station, but he grabbed the order directly by the way. At this time, the platform sent another order to a construction site at the intersection of Baoshuang Road and Tianbao West Road in Yuhuatai District.

　　At 7 pm, the reporter finished delivering the second order from Exit 8 of Yuzui Subway Station and was ready to rush to the construction site where the customer was located. The reporter immediately panicked after seeing that the two places were about 4.1 kilometers apart from the navigation. There were still 3 minutes to time out, so he had to bite the bullet and follow the navigation. When he got closer, he found that there was a cement road under the bridge. The reporter walked about 100 meters in the dark, and he could vaguely see something in the shape of a ladder. When he got closer, he found that it was a step. The reporter pushed the electric car along the narrow slope next to the steps and slowly walked forward. When he saw the bright light, he turned to the Tin Hau Bridge. The reporter turned two or three corners on the bridge before pushing the electric car down the steps at the other end of the bridge. When he went down the steps, he also turned several corners. As soon as the reporter got off the bridge, it was pitch black in front of him again, and he could only identify the concrete road by the dim light of the electric car. After getting off the bridge, the reporter walked all the way along the potholed path next to the Qinhuai New River, and the road ahead became narrower and narrower, and some places were still dirt roads. The reporter drove forward for five or six minutes and turned more than 10 turns before seeing the construction sites on both sides.

　　When the reporter delivered the takeaway to the customer, the platform showed that it had been 18 minutes overtime. The reporter felt guilty and kept apologizing to the other party. The other party also comforted: "It doesn’t matter, the place is difficult to find, and it is at night. Everyone understands, it would be nice if you could deliver it."

　　During the Mid-Autumn Festival and National Day holiday, the reporter sent more than 10 takeout orders to the construction site or the company. Every time they arrived at the construction site, the workers were already waiting at the door. One worker told the reporter: "In order to send the children to school, they usually eat at the construction site canteen. It happened to be the Mid-Autumn Festival, and they ordered more than 20 yuan of Malatang."

　　On the evening of the 5th, the reporter received an order to be sent to the entrance of Yangzijiang Avenue. Since this place is close to the construction site, the reporter thought that the worker had written the wrong location. When calling to confirm, he learned that the other party was a large truck driver who temporarily stopped in Nanjing to rest. The truck driver said on the phone: "This is ordered by my daughter. It doesn’t matter if it is earlier or later. Don’t worry on the road and pay attention to safety."

　　2. Camping and barbecuing have become a trend, and they rush to the riverside to deliver ingredients to tourists on rainy nights

　　At 7:02 p.m. on September 30, the reporter received an order from a hot pot barbecue food supermarket on Wuhou Street, Jianye District. The delivery fee was 8.5 yuan, and it was delivered to the Finless Dolphin Plaza in Sanqiao Wetland Park, 5.2 kilometers away. The reporter specially checked the map before departure, and thought that the destination must cross the Qinhuai New River, pass through Baoshuang Bridge, and get off the stairs. During the actual delivery process, the reporter found that the resistance was even greater, and there were many construction sites. There were many construction vehicles parked on the road next to the construction site.

　　At 7:31 p.m., the reporter finally arrived at the finless porpoise square in Sanqiao Wetland Park, shared the location with WeChat by phone, and found the customer. When the customer received the barbecue ingredients and grill from the reporter, they kept thanking: "Please, please send it all the way!" The customer who originally ordered came to Nanjing from Yiwu, Zhejiang to visit, camped at the finless porpoise square in Sanqiao Wetland Park in the evening, tasted the duck blood fans in Nanjing that day, and liked Nanjing’s food very much.

　　The reporter noticed that during the Mid-Autumn Festival National Day holiday, Riverside Park has become a good choice for tourists from other places and Nanjing citizens to clock in. The reporter went to Yuzui Wetland Park, Sanqiao Wetland Park Finless Dolphin Square and Hexi City Ecological Park to deliver more than 10 orders of takeaway, and only on October 4 at noon, it was sent to Yuzui Wetland Park three times. In Yuzui Wetland Park, a variety of snack cars have attracted tourists from all over the world. Many families ride bicycles in the park to enjoy the scenery everywhere. There are 20 or 30 tents on the grass alone.

　　I ran more than 500 kilometers in 3 or 8 days, and I was often moved during the delivery process

　　On the early morning of October 5, after the reporter finished work, he met a boss selling fried skewers near Hexi Gemdale Plaza, as well as a security guard from a nearby community. The reporter handed the selected skewers to the boss and said, "Roll me two cakes, one is not enough to eat!" After hearing that there were cakes, the security guard next to him also said to the boss, "I will also add two more cakes, how much is it?" The owner of the fried skewers stall said, "No need, I will give it to you." When the reporter said that he wanted to pay, the boss also said, "I don’t want the money, and I will give it to you. It is not easy for everyone to work outside, they are all brothers." Hearing the boss’s words, the reporter and the security guard quickly thanked the owner of the fried skewers stall.

　　In the past 8 days, the reporter cycled more than 500 kilometers and delivered 173 takeaways, generating 1165.3 yuan in delivery income and 55 yuan in activity income. Three orders were deducted 9.74 yuan by the platform for overtime, and one customer was dissatisfied by the platform. 3 yuan was deducted, and 8-day insurance premiums were deducted 20 yuan. A total of 1187.56 yuan was earned.

　　The reporter started to deliver food on the evening of September 28, and the working hours are from 10 am to 2 pm and 5 pm to 1 am the next day. Although the reporter may feel frustrated when the order is overdue or receiving bad reviews from customers, it is with the help of these strangers around him that people no longer feel cold in the early morning rain. Every corner of society is full of care, so that everyone who works hard for their dreams will not feel lonely.

1905 movie network news Since its release, the film has won 136 million box office performance in the first weekend, refreshing the director Diao Yinan’s personal box office record. On December 9, the film once again won 14 million box office, and continued to gain good reputation. The film roadshow also ushered in the last stop, starring Hu Ge airborne in Zhengzhou and surprised the local audience.

14 million box office on working days, with a strong reputation and praise "Treasure Crew"

On December 9th, directed by Diao Yinan, starring Hu Ge and Gui Lunmei, Liao Fan and Wan Qian starred in the movie "The Wild Goose Lake" starring Qidao, the cumulative box office has exceeded 150 million, and the first weekend alone has refreshed the director Diao Yinan’s Berlin Golden Bear Award box office record, and also successfully created the mainland box office record of the Chinese film shortlisted for the main competition unit of the Cannes International Film Festival, becoming a domestic film with a double harvest of word-of-mouth in the same period.

It is reported that the movie "The Wild Goose Lake" took 155 days to shoot, with 82 locations in Wuhan. 370 staff and 3,200 actors contributed 1,307 shots. Behind each amazing number is the absolute implementation of strict standards by all the crew. It is even called "Virgo crew" by Wan Qian, one of the starring actors: Hu Ge exhausted his strength for a shot that repeatedly rolled into the quagmire. Gui Lun magnesium suffered deep second-degree burns and still insisted on shooting. The Wuxing actor was accidentally injured and did not want to affect the shooting effect. The workers carefully put away the equipment after each shooting. The netizens were deeply moved and said: "What a treasure is this crew! The actors are struggling in the weather with a body temperature of more than 50 degrees. All the staff are attentive. I am sorry for the crew’s intentions if they don’t brush it again!"

Hu Ge made an appearance at the roadshow terminal in Zhengzhou, breaking himself and presenting the role interpretation

A few days ago, the film came to Zhengzhou, which was warmly welcomed and loved by the local audience, and also drew a successful end to the film roadshow. Some audience members said excitedly: "I think this film is very good. I am very grateful to Hu Ge for breaking himself and presenting Zhou Zenong."

Hu Ge also responded sincerely: "There are definitely challenges and pressures, I rarely try the big screen, and then there are such excellent teams, producers and directors, and such excellent actors to work together. Whether it is from the performance or from the past experience, it is a new beginning for me. But I feel that I am almost 40 years old. We also talked about it a few days ago, called unbreakable. I think everyone still needs to have some challenges and breakthroughs in themselves, otherwise we will never know where our potential is."

Talking about the glimmer of light on the top of the mountain that Zhou Zenong and Liu Aiai saw in the film, Hu Ge also shared his understanding with the audience: "This light is two interpretations. One is that Zhou Zenong also has a human brilliance. Although he hides in the night most of the time, we can still see his warmth when his life is approaching the end. Another light is hope. It is the 300,000 bounty he exchanged for his life and the hope for his family’s future life. This is the light I hope you can see and feel in this movie, in addition to the neon lights that you see and the lights on the mountains in the distance."

As part of the film’s New Year’s ceremony, Hu Ge and the audience also followed the roadshow convention and tacitly taught the Henan version of the line "Big brother, borrow a fire". The "Borrowing Fire" tour is dotted, running through Guangzhou, Shenzhen, Chengdu, Zhengzhou and other cities, placing the good wishes of the creators and fans, and connecting a warm gathering at the end of the year that belongs to "The Wild Goose Lake".

　　On March 30, 2015, the first new-generation Beidou navigation satellite (the 17th satellite of Beidou Navigation) was successfully launched at the Xichang Satellite Launch Base. Starting from this satellite, Beidou satellites will haveintersatellite linkIt allows various satellites to achieve barrier-free real-time communication in space, allowing for "space conversations" at any time.

　　Beidou No. 2: "Ten years ago, I didn’t know you, you don’t belong to me.

　　What is an inter-satellite link?Inter-satellite link refers to the communication link established between satellites, which can connect multiple satellites together to form a satellite network. Information sharing between satellites is achieved by means of electromagnetic waves, and wireless links with data transmission and ranging functions.The inter-satellite link of Beidou satellites is mainly used to realize information transmission and two-way measurement between Beidou satellites.

　　At present, other navigation systems in the world are studying "inter-satellite link" technology, and each has its own characteristics, such as the UHF band low-speed wide-beam inter-satellite link of GPS in the United States, the S-band low-speed wide-beam inter-satellite link of the Russian GLONASS navigation system, and the Ka-band phased array medium-speed inter-satellite link in our country.

　　Can’t live without you

　　Through the inter-satellite link, the independent operation of the Beidou satellite global system will be realized, the accuracy of orbit determination and timing will be improved, the injection frequency will be improved, and the dependence on ground stations will be reduced, effectively reducing the operation and management costs of the system.The management and maintenance of navigation satellites requires the support and cooperation of the ground station, and the user’s positioning accuracy depends on the accurate determination of the satellite position and satellite time by the ground station, and is injected into the satellite to broadcast to the user.

　　For example, the United States has military bases all over the world, and GPS ground stations can choose the best location around the world to achieve all-weather seamless coverage, high orbit determination accuracy, and high injection frequency. The main control station is located in Colorado, the mainland of the United States, with three injection stations: Ascension Island, Diego Garcia Island, Kwajalein Island, and five monitoring stations (Colorado, Ascension Island, Diego Garcia Island, Kwajalein Island, Hawaii Island).

　　Compared with GPS and Galileo, China’s Beidou relies more on inter-satellite links.

　　For security and other factors, our country has only carried out ground station construction in China, so when the satellite runs to the place where the ground station cannot observe, how does the Beidou navigation satellite work? The answer is that we have inter-satellite links. Each satellite can act as a "router", and it can manage overseas stars through domestic stars without building websites around the world.

　　What if a war breaks out and the ground station is damaged or disturbed? It doesn’t matter, with the interstellar link, our Beidou satellites can be self-reliant and self-sufficient, enter the autonomous operation mode without ground support, and continue to provide high-precision navigation, positioning, and timing services.

　　peacetimeThe high-precision inter-satellite/satellite-earth observation provided by the inter-satellite link can make up for the regional layout defects of the Beidou satellite navigation system monitoring station in our country, manage overseas satellites, improve the injection frequency, and improve the comprehensive service performance of the system.

　　The results show that the orbit determination accuracy of one ground station anchoring satellite-ground link and inter-satellite link data is similar to that of six L-band monitoring stations on the ground except that the orbital plane along the track direction accuracy is slightly worse. Combined orbit determination of inter-satellite link data and L-band data can improve the L-band orbit determination accuracy.

　　Special periodIn extreme cases such as ground station destruction or interference, the Beidou satellite system can operate autonomously with the help of inter-satellite links, providing high-precision navigation, positioning, and timing services within 60 days without ground support.

　　The inter-satellite link provides services for the Beidou system while also providing part-time services: providing communication and measurement and control support for spacecraft, missiles and other aircraft.

　　China’s intersatellite link system has entered the era of "smart phones", representing the technology trend of next-generation satellite navigation systems.

　　The most outstanding features include:

　　1, China’s inter-satellite link system, 70,000 km ranging accuracy to centimeter level, equivalent to seeing a hair strand dozens of kilometers away, the measurement accuracy is higher than GPS.

　　2. China’s inter-satellite link system is like a "mobile phone call", which is used by several people in a house and does not interfere with each other, while the GPS inter-satellite link is a "mass broadcast", which interferes with each other. One line works, and the other lines must be silent.

　　According to the Doppler effect, the electromagnetic wave frequency radiated by an object varies due to the relative motion of the wave source and the observer. The faster the object, the greater the error in the received frequency, and the Doppler shift will affect the communication performance.

　　Therefore, eliminating or reducing the influence of Doppler frequency shift on wireless communication is a problem that must be solved for wireless communication in high-speed motion, and the inter-satellite link needs to complete the fast acquisition and tracking of high-dynamic signals in a very short time.

　　The maximum speed of high-speed rail is 350KM/h, which is about 100m/s, while the relative speed of satellites can reach 5000m/s. The Beidou inter-satellite link can complete a series of complex signal processing such as capture and tracking at extremely high speed in 100ms, and complete the high-speed establishment and handover of the inter-satellite link.

　　Take China as an example.The country farthest from China geographically is Argentina, the distance between Beijing, China and Buenos Aires, Argentina is about 22,000 kilometers, and the farthest distance between the two satellites in space is 70,000 kilometers.

　　This 70,000 kilometers is the furthest distance in the world, but it is also the closest distance. Two satellites are 70,000 kilometers apart, but they always know where each other is, and the accuracy of satellite position prediction can reach the meter level. This accuracy is equivalent to accurately hitting a human-sized target in Argentina in China. This is not a hundred steps through the yang, it is a hundred steps through the needle.

　　The energy of the satellite is provided by two small solar panels. As an energy-limited system, the lower the power of the transmission is required, and the distance between the two satellites is so far. After a long space walk, the electromagnetic wave signal has long been submerged in the vast noise.

　　How low is the signal power that our interstellar link needs to receive? Simply put, it is equivalent to 1/1 billion of the signal power received by our mobile phones. Cunning enemies are everywhere, always playing tricks in the dark, and the interstellar link has its own countermeasures. It can still work freely when the strength of the jamming signal is 100,000 times that of the useful signal.

　　The intersatellite link independently developed by our country can quickly capture satellite signals flashing 70,000 kilometers away from such a low signal power. Through the intersatellite link, China’s Beidou satellite can quickly complete a handshake when flying at high speed in the vast space. After the handshake, the information exchange between the two satellites is completed, and the distance between the satellites is accurately determined. The distance measurement accuracy of 70,000 kilometers can reach 1 cm.

　　In addition to the Ka intersatellite link that has been successfully verified, we also have a laser intersatellite link, which will be an intersatellite highway. Please wait and see.

　　At 7:18 on January 12, 2018, the 26th and 27th Beidou Navigation Satellites developed by the Chinese Academy of Sciences Microsatellite Innovation Research Institute were successfully launched at the Xichang Satellite Launch Center. With the "assistance" of the inter-satellite link, the Beidou-3 project’s global networking and system services are one step closer!
