A Satellite Safety Logic Control System and its Safety State Precise Transition Control Method

With the rapid development of space technology, the role of satellites in space operations is becoming increasingly important. Due to the complex conditions of the space environment, the utilizable environmental features are still ambiguous, so it is necessary to design the satellite safety logic control system. In this study, starting from the analysis of environmental information characteristics, we firstly select the available space environment information characteristics, subsequently we design the satellite safety logic control system. On this basis, we have developed a safety state precise conversion control method, which is referential to the design of safety state conversion strategy of satellite safety system.
