Abstract:Aiming at the problems of many manual intervention links, low level of automation and intelligence, low standardization, incomplete elements and incomplete work after the event in the telecommand operation of the long-term spacecraft operation section, the thesis designs and standardizes the operation process, function module and abnormal alarm disposal strategy of telecommand operation based on the analysis of standardization requirements. The telecommand operation is divided into three stages: before, during and after the remote control uplink. On the existing basis, the modules such as automatic detection of start-up timing legality, automatic state discrimination, automatic driving of time conditions, automatic evaluation of injection results, post event safety disposal, automatic exit, and cyclic alarm push disposal strategy are added to complete the normative preparation of telecommand operation design. Finally, 50 satellites in orbit are selected to verify the standardized telecommand operation and compared with the existing operation. The results show that the standardized telecommand operation significantly improves the safety, reliability and operation efficiency of the uplink work, and improves the stability of the spacecraft in orbit.
