"The person in charge of the long-term management of the satellite should check the satellite telemetry data in real time, analyze the trend of key parameters, and work with the research unit to formulate a emergency response plan for faults, so that when a fault occurs, they could report the situation timely, deal with the problem efficiently with accurate plans, to ensure the stable operation of the satellite in orbit. In addition, they have carried out about 50 on-orbit reconstruction of software on BeiDou-3 project interface update, software independent detection and repair capability improvements, to make sure that the performance of the BDS constellation could be continuously improved and the navigation service optimized."

Storyline


The last satellite of China's BeiDou Navigation Satellite System (BDS) on Tuesday reached the fixed position in its operational orbit, a geostationary earth orbit nearly 36,000 kilometers above Earth, indicating that all the 30 satellites in the BDS-3 system have been switched into a long-term management mode.

On June 23, China launched the last BDS satellite, the 55th in the BeiDou family, marking the completion of the deployment of its own global navigation constellation.

The Xi'an Satellite Control Center, based in northwest China's city of Xi'an, since then has conducted a 24-hour real-time monitoring for the satellite.

It organized observation stations in Weinan, Sanya and Jiamusi to tract the satellite, and calculate its orbit. It also developed a strategy with which it successively implemented multiple orbit maneuvers at apogee, captured the satellite in fixed position, and finally accurately sent it to the target position.

"Judging from the fixed-position capture that we had just completed, currently, the satellite orbit control is accurate with various parameters normal. We will test the satellite platform and the inter-satellite links system in about a week, and the satellite will be officially connected to the network to provide services after each of its subsystems is fully checked," said Liu Yuxiang, engineer at the Xi'an Satellite Control Center.

So far, the satellite has entered an on-orbit long-term management mode.

The control center has established a system with key personnel monitoring the satellites 24 hours a day.

"The person in charge of the long-term management of the satellite should check the satellite telemetry data in real time, analyze the trend of key parameters, and work with the research unit to formulate a emergency response plan for faults, so that when a fault occurs, they could report the situation timely, deal with the problem efficiently with accurate plans, to ensure the stable operation of the satellite in orbit. In addition, they have carried out about 50 on-orbit reconstruction of software on BeiDou-3 project interface update, software independent detection and repair capability improvements, to make sure that the performance of the BDS constellation could be continuously improved and the navigation service optimized," said Ding Mengyu, engineer at the control center.

BDS is one of four global navigation satellite systems in the world. The other three global navigation systems are GPS of the United States, Galileo of the European Union, and GLONASS of Russia.

China has been actively encouraging the cooperation and exchanges between the BDS system and other navigation systems in fields such as construction and application, strengthening compatibility and interoperability, resource sharing, and providing users with more qualified, diversified, safe and reliable services.

Compared with other global systems in the world, the design of the BDS constellation is unique, including medium earth orbit (MEO), inclined geosynchronous orbit (IGSO) and GEO satellites.

The BDS-3 system consists of a total of 30 satellites, including 24 MEO satellites, three IGSO satellites and three GEO satellites.
