An orbit maneuver detection method based on broadcast ephemeris for satellite orbit maneuver detection isproposed. The method detects orbit maneuver by changing the difference between the maximum and minimum values of the satelliteorbit's major half axis. The specific time period during which broadcast ephemeris orbit parameters are unavailable due to orbitalmaneuvers is determined through statistical satellite health identification analysis and the research methods. By analyzing thebroadcast ephemeris of Beidou Navigation Satellite System (BDS) in 2021, the correctness of the orbit maneuver detection methodproposed has been proven. The experimental results show that the method can effectively detect the orbit maneuver ofGeosynchronous Earth Orbit (GEO) and Inclined Geosynchronous Satellite Orbit (IGSO) satellites.
