Xinhua News Agency, Xi'an, July 23 (Lü Binghong, Wang Fan) The Xi'an Satellite Measurement and Control Center recently completed a whole-star health inspection for more than 10 Beidou-2 satellites that are providing regional navigation services.
It is understood that relying on the self-developed data service system, the central scientific and technical personnel completed the inspection process that previously required 10 hours in only 5 minutes, and the efficiency of satellite data analysis has been significantly improved. It is used for satellite mobile process diagnosis, long-term trend prediction, and health status. The analysis laid a solid information foundation.
As China's on-orbit spacecraft management center and aerospace measurement and control network operation management center, Xi'an Satellite Measurement and Control Center has intensive test tasks and has to undertake more than 200 laps of spacecraft tracking tasks every day. To this end, the Party Committee of the Center attaches great importance to the construction of the quality system, and has successively established a leading group and a supervision group for the construction of the quality system, compiling the Quality Sub-Manual, procedure documents, and various operating instructions, and will manage the long-term satellite management, measurement and control network operation, Emergency measurement and control, and abnormal handling are all incorporated into the quality management system, laying a solid institutional foundation for the long-term management of satellites to become regular and scientific.
At present, the center implements a 24-hour on-duty management model. According to Zhang Hailong, an engineer at Xi'an Satellite Measurement and Control Center, they follow the principle of “unified dispatch, overall linkage, standardized procedures, and operation according to the case, fast, accurate, safe, and effective” in fault handling to ensure that the source problem can be quickly found when a fault occurs And implement effective measures for investigation.
"Except for the centralized diagnosis of Beidou navigation system at important nodes in the system construction, we have to hold a regular meeting every week, mainly to report the system operating status and service conditions, and to combine domestic and foreign relevant experience in maintaining satellite navigation systems and research Solve the problems that may occur during the system operation. "Zhang Hailong said.
At the end of 2018, the center's scientific and technological personnel carried out a "health check" on the Beidou navigation satellites in space orbit one by one, performed a health check analysis, and qualitatively plotted the health status radar chart of each satellite, thereby providing a basis for satellite on-orbit operation and maintenance management and achieving a large number On-orbit spacecraft management capabilities have made a new leap.
At present, the development of China's aerospace industry is accelerating, and intelligent and informatized spacecraft management has become an inevitable trend. According to Xu Binglin, director of the long-term management department of the center's spacecraft, for this reason, they will focus on the research and application of spacecraft fault diagnosis, condition prediction, health assessment and life extension management and other technical methods, and work hard to build a world-class spacecraft management center.
