Embodiment Construction
[0025] The present invention will be further introduced below in conjunction with the accompanying drawings.
[0026] figure 1 Shown is the orbit and attitude control method of the present invention, and the method of the present invention will be further described below in conjunction with the embodiments of the present invention.
[0027] (1) Determine the track control disturbance torque
[0028] Due to the thrust deflection and lateral movement of the orbit control engine, installation error, and movement of the center of mass of the star, a large disturbance moment may be generated when the orbit control engine jets, causing the attitude of the star to change.
[0029] Embodiments of the present invention include at least the following two methods for determining the orbit control disturbance torque:
[0030] 1) Model-based analysis method: control the engine installation position according to the track Thrust magnitude and direction The position of the center of ma...
