Abstract

The invention provides a spatial non-cooperative target optical tracking and aiming closed-loop verification system, which comprises a double-star simulator, an optical tracking and aiming device, a dynamical simulator and a comprehensive management and control device, and is characterized in that the double-star simulator comprises a tracking star simulator and a target star simulator which are respectively used for simulating six-degree-of-freedom movement of a tracking star and a target star; the optical tracking and pointing device is used for positioning a target star by adopting a tracking and pointing algorithm to obtain positioning data and sending the positioning data to the comprehensive management and control device; the dynamical simulator is used for generating dynamic characteristics of the target star and / or the tracking star, so that the double-star simulator simulates twelve-degree-of-freedom movement of the tracking star and the target star; and the comprehensive management and control device is used for monitoring the pose information of the double-star simulator and verifying the optical tracking and pointing positioning algorithm according to the pose information and the received positioning data. According to the system, six-degree-of-freedom motion simulation of a target satellite and a tracking satellite can be realized, and high-precision verification can be effectively performed on an optical tracking and pointing positioning algorithm.

Description

technical field [0001] The invention relates to the field of aircraft ground simulation testing, in particular to a closed-loop verification system for optical tracking and aiming of space non-cooperative targets. Background technique [0002] In the process of continuous development of space technology, the research on non-cooperative targets is gradually heating up. Among them, non-cooperative targets generally refer to a class of space targets that cannot provide effective cooperative information, such as failed or malfunctioning spacecraft, abandoned spacecraft, enemy spacecraft, space debris, comets, and asteroids. The on-orbit service technology for non-cooperative targets can not only be applied to on-orbit maintenance, but also is a problem that faces and needs to be solved urgently in the fields of space debris disposal and space attack and defense. [0003] At present, one way in related technologies is to realize the motion state of the target in a space-like wei...

Problems solved by technology

[0003] At present, one way in related technologies is to realize the motion state of the target in a space-like weightless environment through an air-floating platform, and perform pose measurement and ground verification tests on local areas of the spacecraft with significant characteristics. However, this platform can only simulate Three-degree-of-freedom attitude motion of non-cooperative target

Another method proposes an autonomous navigation on-orbit verification system for non-cooperative targets in space, including a target release mechanism, a binocular camera, a data storage and processing module, and a ground receiving and solving system, but this system can only simulate the relative motion of non-cooperative targets , and the calculation amount is large
