摘要
Abstract
Finding the orbital abnormal of orbiting satellite accurately and in time has great meanings. The presented method can find the orbital abnormal of debris or spacecraft effectively, which provide data supports to analyse and verify the collision event computed by space debris collision avoidance system. The orbital abnormal also includes the orbit maneuver and other orbit change.This paper discussed how to analyse the orbital abnormal of LEO satellites using TLE data. Then,a method of using the satellite adjacent elements plus compositive criterion are presented. The basic idea of compositive criterion method is to get each sub criterion and turnover rate using a certain period data of satellites, and each satellite has its own criterion instead of using an settled criterion to all satellites. Analysis showed that compared to using a single element threshold method, the compositive criterion method decreases the missing discrimination and also has a high accuracy of right discrimination. This paper also briefly analyzed other kinds of orbit using the same method.关键词
