Space Debris Removal Method Based on Orbital Ring

Abstract

The invention discloses a method for clearing space debris based on an orbital ring. First, space debris is collected within a local space range of a mission orbit to construct a debris cluster, and then the active spacecraft is controlled to maneuver into the mission orbit and phase with the geometric center of the debris cluster. At the space positions with a difference of 180°, space tethers are used to physically connect the debris cluster with the active spacecraft to form an orbital ring, and then control the active spacecraft to generate disturbances to destabilize the orbital ring to achieve the initial offset of the orbital ring. After the orbital ring is destabilized and offset, the offset continues to increase under the action of the earth's gravity, which makes the debris cluster re-enter the atmosphere. When the debris cluster descends to the upper limit of the atmosphere, the space tether in the orbital ring is released, and the debris cluster The space debris in the air is burnt in the process of falling into the atmosphere, realizing the removal of space debris, and realizing the removal of a large number of space debris at a very low cost of energy consumption, which is of great significance to the future space traffic control and control.

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 ...
