A rope net capture method for space debris based on multi-star coordination

Abstract

The invention discloses a rope net capture system and method for space debris based on the cooperation of multiple sub-stars. Set the control system, communication radar, telemetry device and several attitude control devices, and the communication radar, telemetry device and several attitude control engines are all connected with the control system; The edges of the rope net are evenly joined. The capture of space debris to be captured is realized by controlling the relative movement between the sub-stars and the opening and closing of the capture rope net; based on the flexibility of the relative movement of multiple sub-stars, through cooperative control, the capture rope net is used to wrap the space debris to be captured , can be applied to the space debris to be captured with various geometric shapes and geometric sizes, and the capture of the space debris to be captured can be realized without accurately knowing the information of the space debris to be captured in advance.

Description

technical field [0001] The invention belongs to the field of aerospace, and relates to a space debris capture system and method, in particular to a space debris rope net capture system and method based on multi-substar coordination. Background technique [0002] With the continuous exploration and utilization of space resources by human beings, a large amount of space junk caused by various reasons such as malfunctioning satellites, various explosions, and debris not only occupies precious orbital resources, but also affects the normal operation of spacecraft in orbit. Security poses a serious threat. Especially for large space debris represented by invalid satellites, once a collision occurs, more secondary debris will be produced. Therefore, it is imminent to clean up space debris such as invalid spacecraft. [0003] However, due to the variety of geometric shapes and sizes of space debris, the uncertain motion parameters (most space debris exhibits a state of tumbling m...

Problems solved by technology

[0003] However, due to the variety of geometric shapes and sizes of space debris, the uncertain motion parameters (most space debris exhibits a state of tumbling motion), and there is no special capture and docking mechanism, no cooperative measurement device, etc., making Capturing space debris is extremely challenging
