Digital twinning control method for space debris protection and protection system

Abstract

The embodiment of the invention provides a digital twinning control method for space debris protection and a protection system. The method comprises the following steps: constructing a spacecraft digital twinning body, a debris processing device digital twinning body and a debris digital twinning body; when it is determined that the target fragment digital twinning body collides with the target spacecraft digital twinning body or influences the normal function of the target spacecraft, generating at least one fragment processing strategy; performing analog computation according to each fragment processing strategy, and determining a target fragment processing strategy; and performing control according to the target fragment processing strategy. According to the method of the invention, digital twin simulation is carried out on a known space environment; according to the method, the threat of the space debris is evaluated, and when the space debris threatens the spacecraft, the target debris processing strategy is preferentially determined and controlled, so that the threat of the space debris to the spacecraft is reduced or even avoided, and the safety of the spacecraft in the space is improved.

Description

technical field [0001] The invention relates to the field of space debris protection, in particular to a digital twin control method and protection system for space debris protection. Background technique [0002] Space junk, also known as space debris or orbital debris, is man-made objects in space other than working spacecraft, including debris generated during the launch of launch vehicles and spacecraft, scrapped satellites, and materials shed from the surface of spacecraft. , Solid and liquid materials leaked from spacecraft, rocket and spacecraft explosions, debris produced during collisions, etc. At present, there are more and more spacecraft in space orbit, showing an explosive growth trend. For example, the US Iridium Project and the One Web Project plan to launch thousands to tens of thousands of low-orbit satellites, which will inevitably lead to a significant increase in space junk. The threat of garbage to spacecraft and astronauts will also become increasingly...
