 The last global networking satellite of beidou-3 successfully fixed geosynchronous orbit


After the satellite was launched on June 23, the Xian Satellite TT & C center started the 24-hour real-time monitoring mode, organized the tracking measurement, orbit determination and calculation of Weinan, Sanya, Jiamusi and other TT & C stations. At the same time, the satellite has carried out multiple apogee orbit changes and fixed-point acquisition, and finally delivered the satellite to the destination accurately.

We have developed a large number of plans in advance, optimized the staffing of each post, the preparation of each program, and the sending of each instruction, so as to ensure the safety and accuracy of each measurement and control work in the early track segment to the greatest extent. Center Senior Engineer LAN Baojun said.

According to reports, after the satellite is fixed, Xian Satellite TT & C center will take about a week to carry out the index test of satellite platform and inter satellite link system. After the working state of the satellite has been fully tested, it will be officially connected to the network to provide services.

Prior to this, Xian Satellite TT & C center has implemented more than 600000 program-controlled instructions for 29 beidou-3 satellites that have been connected to the network, and carried out satellite ground link construction, inter satellite chain building, in orbit calibration, measurement and communication, etc., and successfully completed the test task of beidou-3 inter satellite link system. The stability of beidou-3 inter satellite link system has been further verified, and all indicators meet the requirements of global networking. At the same time, the center also carries out multi batch orbit control for several beidou-2 satellites in orbit, so as to ensure the uninterrupted positioning and navigation services, and realize the smooth transition from beidou-2 system to beidou-3 system.
