Title:
SPACE DEBRIS COLLISION AVOIDANCE METHOD AND APPARATUS TAKING ORBIT ALTITUDE ADJUSTMENT TASK INTO CONSIDERATION
Document Type and Number:
WIPO Patent Application WO/2024/045778
Kind Code:
A1
Abstract:
Provided is a space debris collision avoidance method taking an orbit altitude adjustment task into consideration. The method comprises: when a spacecraft has a requirement for consecutive orbital transfer, acquiring a collision risk value of the spacecraft with respect to a piece of space debris within a target duration; and when the collision risk value at a first moment within the target duration is greater than a preset value, controlling the spacecraft at a second moment by using a target control strategy, wherein the second moment is earlier than the first moment; and the target strategy comprises at least one of the following: increasing the orbit control quantity, decreasing the orbit control quantity, increasing the number of instances of orbit control, decreasing the number of instances of orbit control, and combined avoidance control. Further provided is an apparatus for implementing the method. Therefore, propellants, which are used for separately performing orbital transfer control to avoid space debris collision, are decreased, thus improving the operational effectiveness of a spacecraft.
