Space debris clearing method based on orbit ring

Abstract

The invention discloses a space debris clearing method based on an orbit ring, which comprises the following steps of: collecting space debris in a local space range of a task orbit to construct a debris cluster, and controlling an active spacecraft to maneuver to a space position in the task orbit, wherein the phase difference between the space position and the geometric center of the debris cluster is 180 degrees; secondly, physically connecting the fragment cluster with the active spacecraft by using a space tether to form an orbit ring, controlling the active spacecraft to generate disturbance to destabilize the orbit ring so as to realize initial offset of the orbit ring, and enabling the fragment cluster to reenter the atmosphere by using the characteristic that the offset is continuously increased under the action of gravitational attraction after the orbit ring is destabilized and offset; so that in atmosphere re-entering of the debris cluster, when the debris cluster descendsto the position within the upper bound of the atmosphere, the space tether in the track ring is released, space fragments in the fragment cluster are burnt down in the process of falling into the atmosphere, space debris removal is achieved, large-batch space debris removal is achieved with extremely low energy consumption cost, and the space debris removal efficiency is improved. The method is ofgreat significance to future space traffic control and management.

Description

technical field [0001] The invention relates to the technical field of space debris removal, in particular to an orbital ring-based space debris removal method. Background technique [0002] Space debris is space junk produced along with human exploration and use of outer space. As of January 2019, the US Space Surveillance Network (SSN) has cataloged more than 20,000 pieces of in-orbit debris larger than 10cm. These catalogs The amount of debris in orbit only accounts for 0.02% of the total debris, while the weight of tiny debris that cannot be cataloged has reached several thousand tons, and the number exceeds 1 billion. In recent years, with the continuous advancement of science and technology, the threshold for entering space has been continuously lowered, satellite applications have continued to expand in civilian and commercial fields, and the number of micro-nano satellites has increased dramatically, leading to a sharp increase in space debris. [0003] Although it ...
