一种基于卫星轨道长半轴变化的轨道机动探测方法

Method for Orbital Maneuver Detection Based on Change of Long Half Axis of Satellite Orbit

针对卫星轨道机动探测,提出了一种基于广播星历的轨道机动探测方法,该方法通过卫星轨道长半轴最大值与最小值的差值变化探测轨道机动。轨道机动造成广播星历轨道参数不可用的具体时段通过统计卫星健康标识分析以及研究方法得出。通过分析2021年北斗卫星导航系统(BDS)的广播星历,证明了轨道机动探测方法的正确性,实验结果表明该方法可以有效探测地球静止轨道(GEO)卫星和倾斜轨道同步(IGSO)卫星轨道机动。

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