Spacecraft flight control method and device, storage medium and processor

The invention discloses a spacecraft flight control method and device, a storage medium and a processor. The method comprises the following steps: when a flight control event is detected, determining light traveling time between a target spacecraft and a target measurement and control station; determining the sending time of the target uplink carrier according to the optical line time and the planned execution time of the target control instruction; according to the sending time of the target uplink carrier and a preset duration, the target control instruction is sent to the target spacecraft, and the preset duration is smaller than the transmission time of the uplink carrier from the target measurement and control station to the target spacecraft; and performing flight control on the target spacecraft according to the target control instruction. According to the method and the device, the problem that the flight control effect is difficult to conform to expectation due to the fact that the flight control tim
