Embodiment Construction
[0022] To cite a specific embodiment, the constellation adopts a navigation constellation to realize autonomous orbit determination on the satellite and obtain the initial position reference. After that, the navigation constellation fails, and the constellation autonomously maintains the relative position. The laser communication ranging integrated load is used to realize the determination of the relative position of the satellite and the unification of the time on the satellite. The position of each star in the constellation is used to determine the relative position holding requirements of each star, and the target constellation solution is determined after the relative position holding operation is determined. Determine the perturbation adjustment plan through the target constellation, and adjust the perturbation influence through the change and adjustment of the solar wing, so as to achieve the relative position maintenance of multiple stars on the same orbit.
