A Space Debris Avoidance Maneuvering Method for Remote Sensing Satellites Based on Trajectory Keeping Requirements

Abstract

The invention discloses a remote sensing satellite space debris evasion maneuvering method based on ground-track keeping needs. According to an allowable ground track drifting range of remote sensing satellite on-orbit operation, a reference ground track keeping control ring is built, and is divided into different areas, and different maneuvering strategies are determined for a spacecraft according to the different areas, wherein, dangerous intersection possibly happens to the spacecraft, and the track maneuvering evasion space debris collision threat is needed to be carried out, so that the aim of avoiding the collision risk is achieved. According to the method, the ground-track keeping control ring is adopted to serves as the basis for generating the strategy, and the method is simple, efficient, easy to operate and particularly suitable for operation of space debris collision evasion with high timeliness; and the efficiency can be improved, time is saved, the valuable time is earned for space debris collision evasion, and satellite in-orbit operation safety is improved. Meanwhile, the influence of evasion maneuvering on a flying task of the spacecraft is reduced to the greatest extent, and the satellite space debris collision early warning and evasion capacity are improved.

Description

technical field [0001] The invention belongs to the field of spacecraft control, and relates to an orbit control method for low-orbit remote sensing satellites with orbit keeping requirements to avoid collisions for space debris. Background technique [0002] With the development of human space activities, the number of space debris is increasing rapidly, and the risk of spacecraft operating in earth orbit being impacted by debris is becoming more and more serious. Effective solutions must be taken. The several collisions that have occurred so far have all occurred in the low-orbit region, and this region is the altitude at which many remote sensing satellites operate. For remote sensing satellites, which are located in areas where space debris is densely populated, it is necessary to carry out space debris collision warning and avoidance technology research to ensure the safe operation of the spacecraft. For large-sized space debris, there is currently no effective passive...

Problems solved by technology

[0003] At present, when evasion is required for dangerous intersections, in the avoidance strategy design, the adjustment amount for evasive maneuvers is relatively vague, and the general information or literature are all qualitative descriptions, and no quantitative results are given, resulting in greater randomness of control And it is not easy to promote and apply
