Autonomous formation flight control method for networking satellites in batch at initial orbit injection stage

Abstract

The invention relates to an autonomous formation flight control method for networking satellites, in particular to an autonomous formation flight control method for networking satellites in batch at the initial orbit injection stage, which is suitable for formation flight of networking satellites in batch at the initial orbit injection stage. According to the method, a GPS+GNSS+laser radar fusionpositioning scheme is adopted, and absolute orbit determination and relative collision safety determination are achieved; and a decentralized regional self-organized communication network is adopted for information exchange, and self-organized initial orbit correction and mutual orbit phase adjustment are achieved through a networking satellite cluster formation control algorithm based on artificial intelligence. Due to the adoption of the technical scheme, the control method disclosed by the invention can ensure that the dense satellite groups are not collided at the initial stage of orbit injection. The star group automatically corrects the initial orbit deviation and gets close to the standard orbit. Self-organized orbit phase adjustment is carried out to change into a sequential and ordered flight queue, so that ground measurement and control tracking control is facilitated.

Description

technical field [0001] The invention relates to a control method for autonomous formation flight of networked satellites, which is applicable to the initial formation flight of batch networked satellites into orbit. Background technique [0002] At present, the networked satellites mainly use the space-borne GNSS navigation system. The networked satellites cannot be turned on at the initial stage of orbiting. Turn on GNSS. If the networked satellites cannot obtain GNSS data at the initial stage of orbiting, and there are large errors in the orbital information of the separation point of the satellite and rocket provided by the launcher, the dense constellations in the initial stage of orbiting are prone to collision risks, causing unnecessary losses. Contents of the invention [0003] The invention discloses an autonomous formation flight control method in the early stage of batch networking and satellite orbiting, so as to solve any of the above-mentioned and other poten...
