Design of Multiple Lunar Probe Collaborative Control Mode for Lunar Farside Exploration Mission

The multiple lunar probe collaborative control design scheme of lunar farside exploration mission is introduced in this paper. A relay satellite is necessary to provide the relay communication between the exploration probes and the ground TT&C network. In order to solve the complex confederate control problem among the relay satellite,the lunar lander,the lunar rover and the circumlunar satellites in the mission,the description method of associated objects in the collaborative flight control is proposed,and the concept of control object and uplink router object is defined,the principle determination of the above objects and the principle of TT&C resource distribution among uplink router objects are given,and the nominal planning mode,the teleoperation planning mode and uplink telecommand mode are introduced. The design scheme's feasibility is verified by CE-4 mission's space-ground circuit radio joint test and the on-orbit flight of the relay satellite.
