一种编队卫星调相方法
By using the mirror-based phase-adjustment guidance law and acquiring information and calculating control pulse quantities using onboard measurement equipment, the problems of trajectory shape changes and trajectory extension during the phase adjustment process of formation satellites were solved. This enabled flexible adjustment of the ground point time and trajectory stability, avoiding the risk of collision.

AI Technical Summary
Existing technologies are prone to altering the shape of relative motion trajectories or causing trajectory extensions during satellite phasing, making it impossible to flexibly adjust the sub-satellite point time.
The mirror-image phase-modulation guidance law is adopted. Relative position and velocity information are obtained through onboard measurement equipment. The control pulse and pulse application time expression are designed. The control pulse quantity is calculated using the CW equation. The control pulse is applied only in the Z-axis direction to change the time at the nadir.
It enables arbitrary changes to the sub-satellite point time within half a cycle, reduces the waste of phase adjustment time, maintains trajectory stability, avoids collision risks, and the trajectory still runs within the initial ellipse.
