At 12:00 on June 2, 2022, Beijing time, China's Long March 2C carrier rocket successfully launched the first orbit nine satellites of "Geely future travel constellation" at Xichang Satellite Launch Center in the form of one arrow and nine satellites. The satellite successfully entered the predetermined orbit and the launch mission was a complete success. Through the construction of "Geely future travel constellation", Geely Holding Group will build a "Heaven Earth integration" high-precision space-time information system. Geely's foresight As early as December 15 last year, Geely tried to send two of its satellites to the sky. At that time, China's kuaizhou-1a carrier rocket was carrying out the mission. Unfortunately, the flight was abnormal after the rocket ignited, resulting in the failure of the launch mission. This success indicates that Geely has taken a big step in its commercial space layout. According to the official information given by Geely Holding Group, this plan has been laid out for a long time. The satellites launched in these two times were self-developed by Zhejiang spacetime Daoyu Technology Co., Ltd. (hereinafter referred to as spacetime Daoyu). Its Taizhou satellite super factory leaves the factory. Geely Holding Group has five group companies, namely Geely Automobile Group, Volvo car group, Geely technology group, Geely new energy commercial vehicle group and Mingtai group. Automobile is the main business, and the three group companies other than Mingtai group are directly related to automobile manufacturing. The protagonist of the Geely satellite launch, spacetime Daoyu, belongs to Geely technology group. Spacetime Daoyu was founded in November, 2018 with a registered capital of RMB 500million. Its legal representative is Wang Yang and LiShufu is the chairman. The main shareholder is Hangzhou maijie Investment Co., Ltd., an investment company under Geely Holdings (holding 70% of the shares), whose business scope includes satellite communication system, communication technology, data processing technology, telecommunications business, etc. Before Geely invested in spacetime Daoyu, there had been many official news to seek "integration of heaven and earth". Launching satellites is only an application level. Spacetime Daoyu is mainly responsible for the research and development of satellites and can provide solutions for the integration of satellite communication and navigation. Geely holdings is committed to creating a hard core technology ecology. It is the first enterprise in China that makes cars and stars by hand. The large-scale integration of the aerospace industry and the automotive industry will bring about far-reaching changes in the business application scenarios. What is the intention of satellite layout As we all know, the current automatic driving technology mainly relies on the millimeter wave radar, laser radar, camera and other equipment provided by the vehicle, through a large amount of AI learning and in combination with high-precision maps. However, today's satellite positioning system can only achieve the sub meter level, and can cope with the L2 level. However, for the l3l4 level autopilot with higher accuracy in the future, there is still a gap in the current positioning accuracy. Compared with medium and high orbit satellites, low orbit satellites have lower cost, difficulty, launch cost and weight, and are more suitable for commercial companies to layout their own positioning and navigation systems. Spacetime Daoyu specializes in LEO satellites. Due to the low orbit height of the satellite, the transmission delay is short and the path loss is small, so the positioning accuracy is higher. By virtue of low orbit satellites, space-time Daoyu has laid out the whole industrial chain of commercial aerospace and created a low orbit satellite constellation, which can enable Geely Holding's automobile brands to realize the transformation of electrification and intelligence. In addition, it also provides all-round services for autonomous driving, marine, UAV, logistics, surveying and mapping and other fields. The ground-based ppp-rtk space-time information network, beidou-3 module and terminal products that have been built by the first track nine satellites in combination with the space-time Daoyu will realize the integrated application of remote sensing, navigation and communication technologies and provide an all-round three-dimensional guarantee for future travel. This successful launch has not only accumulated Geely's experience and confidence in commercial aerospace, but also will soon bring massive data resources to Geely. Geely wants to be China's Tesla? Tesla's "star chain" plan is the only enterprise that has established a link between the space field and the automotive field. It is understood that at present, the "star chain" program has launched more than 2300 satellites, which is even more than 10 times that of China's currently in orbit satellites. The "star chain" plan intends to build a satellite Internet from LEO satellites, covering the whole world, so that people everywhere can access the Internet at any time. Generally speaking, it is equivalent to moving the base station to the sky. The significance of Geely's satellite launch lies in "precise positioning". With the development of autopilot into deep water, the status of satellite in auto drive system is more and more recognized. According to the white paper on high precision satellites for intelligent connected vehicles (2020 version) prepared and released by the autonomous driving map and positioning working group of China intelligent connected automobile industry innovation alliance, L3 level autonomous driving will become a watershed in the development of the industry. Starting from L3 level, high-precision map will become the rigid demand for autonomous driving and the key link to complete safe, reliable and stable driving. At present, in terms of navigation and positioning, there are actually four major satellite navigation systems in the world, namely, GPS of the United States, GLONASS of Russia, Galileo of the European Union and Beidou of China. However, the global GNSS satellite navigation signal is not developed for automatic driving, and it can no longer meet the demand for L3 level automatic driving. Therefore, building a dedicated intelligent Internet connected satellite system is the key for car companies to win the future. Obviously, the meaning of "Geely future travel constellation" is quite different from the starting point of Tesla's "star chain plan". The former is more focused on serving their old car industry. At the same time, the "Blue Star Guardian" public welfare project of Geely Holding Group uses aerospace technology to empower marine protection, continuously monitor the marine ecological environment through high-performance remote sensing AI data services, monitor and manage natural and industrial hazards such as floating garbage, marine oil spills, red tide Enteromorpha prolifera, etc., help marine ecological protection and promote the sustainable development of the marine environment. The aerospace field is an emerging and key field of military civilian coordinated development. As an emerging industry with strong technological innovation, high economic quality and efficiency, and both military and civilian attributes, commercial aerospace is an extremely important and emerging growth pole for China's economic development, and the only way for China to move forward from a aerospace power to a aerospace power. This time, Geely successfully stood out and became the first automobile industry company in China to contact with space, which not only highlighted its industry position, but also painted a heavy color on China's automobile industry and commercial aerospace field.
