Passive target synchronous racemization capture operation method based on space multi-arm contact

Abstract

The invention discloses a passive target synchronous racemization capture operation method based on space multi-arm contact. The method comprises the following steps: step 1, making a service spacecraft enter an orbit of a space rolling target and synchronously moves along with the orbit of the space rolling target; step 2, obtaining the measurement information of a space rolling target by the service spacecraft; step 3, optimizing the base track of the service spacecraft and all joint tracks and driving force input of the mechanical arm in an offline mode, forming a track for contact racemization capture and serving as a reference track; step 4, generating an extended reference trajectory based on the reference trajectory obtained by optimization; and step 5, executing a task, tracking the expanded reference trajectory, and realizing contact racemization capture of the space rolling target. Aiming at a spatial non-cooperative rolling target, any capture point on the target is not needed, the target can be automatically racemized, and capture and operation of the target are achieved at the same time when racemization is completed.

Description

technical field [0001] The invention belongs to the technical field of space capture, in particular to a passive target synchronous derotation capture operation method based on space multi-arm contact. Background technique [0002] With the continuous exploration and utilization of space resources by human beings, a large amount of space garbage caused by various reasons such as malfunctioning satellites, various explosions, and debris has gradually caused a shortage of space resources, and at the same time caused serious damage to space security. threaten. It is imminent to clean up invalid spacecraft or orbital junk, but due to the non-cooperative nature of space junk (for example, no special capture and docking mechanism, no cooperative markers for measurement, and often in a state of unstable attitude), it is extremely challenging to capture sex. [0003] The existing capture methods mainly include mechanical arm capture and flying net capture. Among them, the capture...
