Abstract

The invention discloses a space non-cooperative target electromagnetic eddy current racemization capture device and a method thereof. The device includes a working spacecraft equipped with solar panels; an observation system and a robotic arm are provided on the working spacecraft; the observing system is used to estimate the direction and speed of the target rotation, and the electromagnet is provided with an electromagnet for derotation; an end effector for capturing the target after the race is provided at the end of the robot arm. Compared with the small satellite formation-based race andcatch system, the present invention has advantages in control difficulty, fault tolerance and service life.

Description

technical field [0001] The invention belongs to the technical field of space non-cooperative target capture, and in particular relates to an electromagnetic eddy current spin-down capture device and method for space non-cooperative targets. Background technique [0002] Space non-cooperative target refers to any spacecraft that is not designed for docking or capture, that is, the target is not equipped with a gripping mechanism (handle) for robotic arm capture and cooperative markers and feature blocks for auxiliary measurement, or Any spacecraft that cannot perform attitude control and roll freely in space. Generally, it includes satellites without cooperative components installed by one’s own side and satellites with cooperative components installed by one’s own side but exhausted of fuel, satellites with malfunctioning attitude and orbit control systems, failed satellites of one’s own side, space debris, and the opponent’s spacecraft. Existing spacecraft in orbit are bas...
