Research on the Method of GEO Satellite Maneuver Detection Based on TLE Data

This paper studies and proposes a TLE-based geosynchronous orbit satellite (GEO) maneuver detection algorithm. The algorithm uses the Gaussian motion equations, and the inclination change and velocity difference under the RSW coordinate system of adjacent epoch are calculated for target maneuver detection. At the same time, owing to the GEO's characteristics of high maneuver frequency and uncertain thrust magitude, a threshold setting method based on sliding window is designed to effectively improve the maneuver detection rate. The accuracy and effectiveness of the algorithm are verified by simulation examples based on the public TLE data.
