Example Embodiment

[0032] The present invention will be described in detail below in conjunction with the drawings and embodiments of the specification.

[0033] Such as figure 1 As shown, the present invention is a method for autonomously tracking and maintaining space non-cooperative maneuvering targets on a satellite, and the specific steps are as follows:

[0034] (1) Establish the relative motion model of tracking spacecraft and space non-cooperative target spacecraft.

[0035] For the method of autonomously calculating orbital changes on the tracking spacecraft, the relative motion model that needs to be adopted can adapt to the computing resources on the satellite. When the tracking spacecraft is tracking and monitoring a non-cooperative target spacecraft in space, the relative distance between the two spacecraft is very close, and the perturbation effects are basically the same. Therefore, the relative motion model of the tracking spacecraft and the space non-cooperative target does not consid...

Abstract

The invention provides a tracking-maintaining and orbit transfer method of an on-satellite autonomous non-cooperative maneuvering target. A typical C-W equation serves as a relative motion model, a relative motion relation between a tracking spacecraft and the spatial non-cooperative maneuvering target is linearized, the computational complexity is reduced, and on-satellite autonomous computing isrealized on the premise that capability of on-satellite hardware equipment is limited. Capability constraint of the tracking spacecraft is taken into full consideration during design of tracking-maintaining and orbit transfer strategies, the maximal ignition time constraint and shortest time interval constraint between twice ignition of a thrust of the tracking spacecraft are introduced, so thatthe design method of the tracking-maintaining and orbit transfer strategies of the spatial non-cooperative maneuvering target is realized under engineering constraints fo the tracking spacecraft.

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 ...
