A Method of Tracking and Maintaining an Autonomous Non-cooperative Maneuvering Target on a Satellite

Abstract

The invention provides a method for tracking and maintaining the orbit of an autonomous non-cooperative maneuvering target on a star, using the classic C-W equation as a relative motion model to linearize the relative motion relationship between the tracking spacecraft and the non-cooperative maneuvering target in space On the premise of limited capacity of on-board hardware equipment, on-board autonomous computing can be realized. At the same time, in the design of the track-and-hold orbit change strategy, the ability constraints of the tracking spacecraft are fully considered, and the maximum ignition time constraints of the thrusters of the tracking spacecraft and the minimum time interval constraints between two ignitions are introduced to realize the tracking of the spacecraft under engineering constraints. Design method of space non-cooperative maneuvering target tracking and maintaining orbit change strategy.

Description

technical field [0001] The invention relates to an on-board autonomous non-cooperative maneuvering target tracking, maintaining and orbit changing method, which can be applied to space non-cooperative targets with maneuvering capabilities to perform tracking, maintaining and monitoring tasks, and belongs to the technical field of space on-orbit services. Background technique [0002] With the continuous deepening of human exploration of space, higher requirements are put forward for space technology. Problems such as on-orbit capture and maintenance of spacecraft and space debris removal have become technical problems that need to be faced and solved urgently in the development of aerospace technology. Among them, the spacecraft's short-range tracking and monitoring, rendezvous and docking, and capture of non-cooperative targets are extremely complicated. In particular, some non-cooperative targets in space have the ability to maneuver and change orbits. During the process ...

Problems solved by technology

Among them, the spacecraft's short-range tracking and monitoring, rendezvous and docking, and capture of non-cooperative targets are extremely complicated

In particular, some non-cooperative targets in space have the ability to maneuver and change orbits. During the process of tracking, surveillance or capture, non-cooperative targets perform maneuvers to change orbits and change their original orbits, thus making the tracking spacecraft lose their targets.
