Embodiment Construction
[0063] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0064] Taking the non-fixed-time double-pulse rendezvous and docking optimization problem as an example, the X-axis of the relative coordinate system is along the flight direction of the target spacecraft in the orbital plane, the Z-axis points from the center of mass of the target spacecraft to the center of the earth, and the Y-axis conforms to the right-handed orthogonal coordinate system. It is perpendicular to the orbit plane, and the following CW equation is used to approximate the description to establish the optimization model of the spacecraft pulse rendezvous trajectory:
