Embodiment Construction

[0082] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0083] Such as figure 1 As shown, the on-orbit verification system for autonomous relative navigation of space non-cooperative targets based on image information includes a binocular camera communicating with the on-board data bus, a target release mechanism, a data storage module, and a data processing module; The receiving system communicates through the data transmission system;

[0084] The target release mechanism receives instructions from the on-board data bus to release the space-borne target at a speed that meets the on-orbit verification, so that the released space-borne target has the characteristics of a space non-cooperative target and enters the measurement range of the binocular camera;

[0085] The binocular camera receives power-on instructions from the on-board data bus, as well as satellite time, satellite orbit, satellite attitude an...

Abstract

A spatial non-cooperative target autonomous relative navigation in-orbit validation system based on image information is disclosed. A target release mechanism receives an instruction from an on-boarddata bus to release a space-borne target, and the space-borne target has spatial non-cooperative target characteristics and enters the measurement range of a binocular camera; the binocular camera carries out stereoimaging and transmits sidereal time, satellite orbit, satellite attitude angle, binocular camera installation azimuth and pitch angle information to a data memory module; a data processing module carries out autonomous relative navigation calculation in real time, and calculated corresponding sidereal time and calculation results are sent to a ground data receiving system through adata transmission system; and the ground data receiving system stores the received data and carries out relative navigation calculation to obtain relative orbit and observation residual error of the non-cooperative target, and the calculation results are compared with the calculation results downloaded by the data transmission system so as to validate the on-board autonomous relative navigation.

Description

technical field [0001] The invention relates to an on-orbit verification system for autonomous relative navigation of space non-cooperative targets based on image information, which can be applied to complex aerospace tasks such as spacecraft on-orbit service and maintenance, space debris cleaning, etc. The problem is to build a kind of on-orbit verification on the satellite, and provide a technology for the on-orbit verification on the satellite. Background technique [0002] With the continuous deepening of human exploration of space, higher requirements are put forward for space technology. Issues such as on-orbit service and maintenance of spacecraft and space debris removal have become technical problems that need to be faced and resolved urgently in the development of aerospace technology. [0003] Cooperative targets are usually equipped with auxiliary identification and response devices, which can be coordinated by commands. The state perception and measurement rel...
