A digital twin control method and protection system for space debris protection

Abstract

An embodiment of the present invention provides a digital twin control method and protection system for space debris protection, wherein the method includes: constructing a digital twin of a spacecraft, a digital twin of a debris processing device, and a digital twin of debris; When the digital twin of the target spacecraft collides with the target spacecraft or affects the normal function of the target spacecraft, generate at least one debris handling strategy; perform simulation calculations according to each debris handling strategy, and determine the target debris handling strategy; according to the target Fragmentation policy control. The technical scheme of the present invention evaluates the threat of space debris by performing digital twin simulation on the known space environment, and when space debris poses a threat to the spacecraft, optimally determines the target debris processing strategy and controls it to reduce or even avoid space debris. The threat of debris to spacecraft is conducive to improving the safety of spacecraft in space.

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...
