At 12:00 on June 2, the Long March 2C carrier rocket ignited and lifted off at the Xichang Satellite Launch Center of China. It launched Geely constellation 01 satellites in the form of "one arrow, nine satellites", and then put the satellites into the predetermined orbit. The launch mission was a complete success**
This group of satellites is used for the first orbital deployment test of the low orbit future travel constellation of Zhejiang spacetime Daoyu Technology Co., Ltd. (hereinafter referred to as "spacetime Daoyu") subordinate to Geely technology group. Through the construction of travel constellations in the future, spatiotemporal Daoyu will build a high-precision spatiotemporal information system integrating heaven and earth, and combine multi-dimensional carriers such as automobiles and consumer electronics to enable smart travel, unmanned systems, smart cities and other fields.
At the beginning of 2021, spacetime Daoyu started the development of the future travel constellation 12 stars, and completed the design, production and large-scale system planning of 12 100 kilogram satellites within 15 months. The first orbit nine satellites of the future travel constellation launched this time are mass-produced low orbit satellites independently developed by spacetime Doyu of Geely technology group. They are delivered from the satellite super factory under spacetime Doyu, with a design life of 5 years.
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 three-dimensional guarantee for future travel.
Through its own ground measurement and operation control system, spacetime Daoyu realizes the control and data reception of the first orbit nine satellites of the future travel constellation, and ensures the automation, intelligence and high availability operation of the first orbit satellites. The ground measurement, operation and control network is composed of remote earth stations, satellite task control main center, satellite task control standby center and ground support network. It supports the functions of multi satellite and multi task automatic planning, satellite status automatic interpretation and early warning, daily task automatic execution and remote unattended earth stations. It can provide automatic measurement, operation and control services for single satellite, multi satellite, single constellation and multi constellation, greatly reducing the complexity of constellation operation management.
In the future, spatiotemporal Daoyu plans to build an intelligent ground station group integrating measurement, operation and control in Qingdao, Taizhou, Korla, Chengdu, Harbin and other places, and to build overseas stations in "the Belt and Road" countries, Europe and other regions, so as to achieve 100% measurement and control coverage in China and large-scale coverage in the world, and meet the needs of constellation measurement, operation and control services.
In this mission, the number of satellites launched by chang'er-c rocket at a single time reached a new high. The Long March 2C carrier rocket is a normal temperature liquid carrier rocket developed by the first Academy of China Aerospace Science and Technology Corporation. It mainly performs the launch tasks of solar synchronous orbit and other low orbit satellites. The chang'er-c rocket used in this mission is a two-stage configuration. The total length of the whole rocket in this state exceeds 42 meters, and the takeoff mass of the whole rocket is 242 tons. This is the fourth launch mission of the chang'er-c rocket this year. It is only more than ten days since the last successful launch of this type of rocket (May 20).
This is the 422nd launch of the long march series of launch vehicles.
