空间站舱段平转式转位方案设计与验证OA北大核心CSTPCD

According to the mission requirement that the direction of China Space Station labora-tory module to the sky or the earth should remain unchanged before and after transfer,a flat transfer scheme is proposed in this paper,and a module transfer implementation scheme based on flat transfer mechanism is designed.During the module transfer,a passive gravity gradient stable attitude is taken by space station for flight,which enables the space station to stabilize its own di-rection when it stops active attitude control.By designing and selecting appropriate transfer mis-sion window,it can ensure unblocked track telemetry control link and sufficient sunlight during the whole transfer process,improving the mission security and reliability.Through ground tests and orbital laboratory module transfer missions implementation,the space station module flat transfer scheme has been comprehensively verified.
