A Synchronous Derotation Capture Operation Method for Passive Targets Based on Spatial Multi-arm Contact

Abstract

The invention discloses a passive target synchronous derotation capture operation method based on space multi-arm contact, which comprises the following steps: Step 1: The service spacecraft enters the orbit of the space tumbling target and moves synchronously with the orbit of the space tumbling target; Step 2 : The service spacecraft obtains the measurement information of the space tumbling target; Step 3: Offline optimization of the base trajectory of the service spacecraft, the trajectory of each joint of the manipulator and the input of the driving force, forming a trajectory of contact derotation capture, as a reference trajectory; step 4: Generate an extended reference trajectory based on the optimized reference trajectory; Step 5: Execute the task, track the extended reference trajectory, and realize the contact derotation capture of the space tumbling target. The invention aims at the non-cooperative tumbling target in space, does not need any capture point on the target, can derotate the target by itself, and realizes capture and operation of the target at the same time when the derotation 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 faulty satellites, various explosions and debris has gradually shown a shortage of space resources, and it has also caused serious problems to space security. threaten. Cleanup of failed spacecraft or orbital junk is imminent, but capture is challenging due to the non-cooperative nature of space junk (eg, no dedicated capture docking mechanisms, no cooperative marker blocks for measurements, and often in a state of attitude instability) sex. [0003] The existing capture methods mainly include robotic arm capture and flying net capture. Among them, robotic arm capture usually requires a capture do...
