After nearly 8 days' flight, the last networking satellite of Beidou satellite navigation system was successfully positioned in the geosynchronous orbit 36,000 kilometers away from the Earth at 14: 05 this afternoon. At present, the satellite antenna has been deployed, the payload has been turned on, and the satellite is working normally in orbit. At this point, the TT&C Center of Xi 'an Satellite successfully completed the TT&C mission of the early orbit section of Beidou Terminal, and all 30 Beidou-3 satellites were transferred to the long-term management mode. After the last networked satellite of Beidou satellite navigation system was launched on June 23rd, Xi 'an Satellite Monitoring and Control Center started a 24-hour real-time monitoring mode for this satellite. According to the flight control plan, they organized several monitoring stations such as Weinan, Sanya and Jiamusi. Tracking measurement satellites, as well as tracking measurement and calculation; At the same time, they formulated a perfect orbit transfer strategy, and carried out apogee orbit transfer and fixed-point capture on the satellite many times, and finally delivered the satellite to the target point accurately. At present, the Beidou-3 satellite has entered the on-orbit long-term management task mode, and Xi 'an Center has established a system of one satellite, one responsibility and one backup, so that each satellite can be managed at all times.
What does Beidou mean to measure whether a country is a space power? There is a strict and complicated index system. To build China into a space power, it is necessary to keep jumping along this index system and complete the historic leap from quantitative change to qualitative change. But for the public, there is a more intuitive angle to measure whether a country is a space power, that is, its performance in various aerospace fields. Throughout the world's major space powers, especially the United States, it is not difficult to find that space powers have "three standards": an independent, stable and reliable global navigation system, a self-built and operated space station system, and mature deep space exploration capabilities such as exploring the moon and Mars.
Accordingly, we can proudly say that the successful flight of the last star of Beidou-3 marks that the Beidou navigation system that China has worked hard for 26 years and generations has finally completed the task of building a global constellation. The dedication of world-class space infrastructure to the international family indicates that China has not only grown into a world-famous space power, but also taken a big step towards building a space power in an all-round way.
