Description

technical field

[0001] The present application relates to the field of aerospace technology, in particular to an attitude-orbit coupling control method and system thereof. Background technique

[0002] At present, the orbit control and attitude control of the spacecraft adopt the decoupling control method. The orbit control adopts the main thrust engine that passes through the center of mass of the spacecraft, and the attitude control adopts a small thruster that does not pass through the center of mass of the spacecraft and only generates a moment around the center to generate a force couple.

[0003] Specifically, such as figure 1 with 2 As shown, the attitude control uses three groups (6) attitude control nozzles 2 installed around the side wall of the vehicle body 1 for attitude control, the first attitude control nozzle 21, the fourth attitude control nozzle 24 or the third attitude control nozzle 21. The control nozzle 23 and the sixth attitude control nozzle 26 sim...
