Abstract

The invention discloses a space debris collision early warning method, which is characterized by comprising a space debris positioning system and an early warning system; the early warning system is used for calculating the relative motion trail of space debris under a spacecraft orbit coordinate system by utilizing spacecraft orbit information through space debris observation information detectedby a microwave radar on a spacecraft, calculating the minimum distance of the space debris relative to the spacecraft in the future T time, giving early warning information by judging the minimum distance for multiple times, and starting an orbit avoidance program for avoiding collision. Compared with the prior art, the invention aims to provide the space debris collision early warning method, which is provided for the collision harm of the space debris to the satellite, has a good actual processing effect, and can be widely applied to space debris monitoring.

Description

technical field [0001] The present invention relates to the technical field of collision early warning methods, and more specifically relates to a space debris collision early warning method. Background technique [0002] The number of space debris in space is increasing every year, especially in recent years, which poses a serious threat and damage to the safe operation of spacecraft in orbit, and once a collision occurs, the wreckage and debris will cause even worse space conditions. environment, posing a greater threat to the safety of space activities. At present, 94% of the objects in orbit are space debris with no use value. Conventional monitoring methods for space debris can be divided into two types: ground-based monitoring and space-based monitoring. Ground-based observation is easily restricted by weather, geographical location and time, and has limited monitoring range, poor detection timeliness, slow data update rate, and At present, the ground can only observ...
