Satellite remote command operational method

Abstract

The present invention relates to a telecontrol command operation method of a satellite. A telecontrol command of the satellite under a routine operation is encapsulated into a relative time telecontrol command group, and is memorized in a computer on the satellite at first, or the relative time telecontrol command group is marked on the ground, and then the memorized relative time telecontrol command group is updated by the computer on the satellite. When the relative time telecontrol command group is needed to be executed, the relative time telecontrol command group is started up according to one telecontrol command sent from the ground. The computer on the satellite logically manages the relative time telecontrol command group. By adopting the designing of the relative time telecontrol command group, the telecontrol operation steps on the ground are simplified, the using of the channel is saved, the operational failure probability of the satellite is reduced, the safety of the satellite is enhanced, and the management flexibility of the satellite is enhanced.

Description

technical field [0001] The invention relates to a satellite-borne remote control command operation method, which is suitable for the remote control command operation of all satellites. Background technique [0002] At present, there are two commonly used satellite-borne remote control command operation methods. One is the real-time remote control command operation method. An operation method for commanding and controlling satellite actions. This remote control operation method has a very limited application range and is only suitable for the situation where the satellite is within the visible range of the ground measurement and control station; the other is the absolute time remote control command operation method. This operation method takes the absolute time of the satellite as the driving condition. When the satellite is within the visible range of the ground measurement and control station, the ground measurement and control station compiles the remote control instructio...

Problems solved by technology

[0003] For satellites with simple payload tasks, the existing remote control command operation method can meet the current mission requirements, but with the advancement of science and technology, the functions of satellite payloads are diverse, and the working parameters of various payload equipment are relatively complicated, requiring frequent The remote control command injection operation is carried out. In the working process of the existing remote control operation method, the command that should be executed may not be successfully sent to the satellite due to the unstable operation of the satellite-ground link or some other accidental factors, thus As a result, some instructions in a certain working mode are not executed. Generally, the operation of this mode will be incomplete. In severe cases, it may cause fatal damage to the satellite.
