AI Technical Summary
In existing technologies, conventional elliptical orbital flight methods within the orbital plane cannot meet the needs of complex and special on-orbit service missions, and cannot achieve flexible setting of non-elliptical orbital trajectories.
A trajectory planning method based on spatial trigonometric functions is adopted. By defining eleven flight parameters, including flight radius, angle, and time, the formation vector in the flight trajectory is designed and transformed into the orbital coordinate system, so as to realize the flexible setting of flight plane, size, shape, time, number of circles and initial position.
It achieves high flexibility and universal adaptability in orbital trajectory, can meet a variety of on-orbit service needs, and is simple, easy to operate, and can be autonomously implemented on the satellite.
