Abstract
In response to the lack of systematic recovery strategies for telemetry loss problem en-countered by satellites in orbit.A systematic recovery strategy is proposed by establishing a tree decomposition diagram of telemetry loss fault cause classification and countermeasures,consis-ting of a three-layer model of fault cause classification,fault root localization,and response and recovery strategy.At the level of fault root localization,specific recovery strategies are formula-ted based on the classification of telemetry loss fault causes,including satellite software FDIR(fault detection,isolation and recovery)autonomous fault diagnosis and recovery strategies,as well as ground manual command recovery methods.The logical flow of recovery strategies is ana-lyzed for each method and verified by in-orbit operation practice.As a result,the proposed recov-ery strategy is demonstrated to be available in real time to recover telemetry,and mitigates the impact on telemetry loss fault.The development direction of countermeasures for satellite telem-etry loss faults is discussed by improving the intelligence and autonomy of onboard software,which can provide reference for the design of in orbit satellite fault recovery.关键词
