一种基于CEI的GEO目标滑窗式机动探测方法

A sliding window maneuver detection method for GEO targets based on CEI measurement

为了进一步提升地面跟踪站的监视预警能力,提出一种基于连线相位干涉测量(CEI)的地球静止轨道(GEO)目标滑窗式机动探测方法:立足于CEI的GEO短弧段定轨和预报,基于GEO卫星位保机动的持续小推力和轨道缓慢渐变特性,提出一种针对GEO目标尤其是非合作GEO目标的滑窗式准实时机动探测方法;并利用亚太七号和中星十号卫星的CEI仿真和实测数据进行机动探测。结果表明,东西机动和南北机动捕获与卫星发动机的点火时刻基本保持一致,机动探测延迟量均小于10 min;能够实现GEO目标的准实时机动告警。

In order to further improve the surveillance and early warning capability of ground tracking stations,the paper proposed a sliding window maneuver detection method for geostationary Earth orbit(GEO)targets based on connected element interferometry(CEI)measurement:CEI-based GEO short-arc orbit determination and orbit prediction were demonstrated,and based on the continuous small thrust and slow orbital fading characteristics of positioning-maintaining maneuvers of GEO satellites,a sliding window quasi-real-time maneuver detection method for GEO targets,especially non-cooperative GEO targets was given;then maneuver detection experiments were carried out using both the simulated and measured CEI data of APSTAR 7 and Zhongxing 10 satellites.Results showed that the east-west maneuver and north-south maneuver captures would be basically consistent with the ignition moments of the satellite engines,and the maneuver detection delay less than 10 min,indicating that the proposed method could help realize the quasi-real-time maneuver warning of GEO targets.
