A super-fast rendezvous and approach short-distance guidance method and device

By adopting a combination strategy of CW guidance and line-of-view guidance during the rending and docking process, using the preset terminal anchor points of the long-distance guide segment to control rending and docking in segments, the problem of insufficient close-range autonomous control period in traditional rending and docking is solved, and the accuracy and safety of 2h ultra-fast rending and docking is achieved.

Abstract

The present invention provides an ultra-fast rendezvous and proximity guidance method and device for close-range guidance. The method includes: obtaining a preset terminal anchor point of a tracking spacecraft in a long-distance guidance section; taking the preset terminal anchor point as an initial condition, the tracking spacecraft adopts a CW guidance and line-of-sight guidance strategy to enter the proximity section, and then enters a translation and approach section including an extreme speed section and a safe approach section to complete close-range guidance; wherein, line-of-sight guidance is performed after 3 times of CW guidance. The ultra-fast rendezvous and proximity guidance method provided by this solution omits the homing section, reduces the close-range guidance time, and can achieve ultra-fast rendezvous and docking within 2 hours.
