1GEO卫星东西机动监视与移动窗口轨迹拟合显示文摘快速获得可靠的实际机动点火时段,可以有效缩短GEO卫星在整个导航星座中的不可用时段。针对GEO卫星的星下点运动特性,本文提出同步根数加东西漂移加速度的运动参数集,验证了七参数模型对10min窗口轨迹拟合的可行性。基于东西定点机动的工作原理,提出联合半长轴拟合窗口序列和测站测距拟合-预报残差均方根窗口序列的机动监视方法。利用C波段转发测距资料,对某GEO卫星包含变轨弧段在内的1d数据进行开窗运动学拟合分析,验证了机动检测方法的有效性和灵敏性。杜兰 张中凯 李晓杰 王若璞 刘利 郭睿 2014测绘学报2014,43,3:4
2Satellite orbit determination combining C-band ranging and differenced ranges by transfer显示文摘The constraint in the transverse direction of satellite orbit with differenced ranges between master station and slave stations by transfer as an angular observation data is explained in theory. Differenced ranges in combination with C-band ranging by transfer were used in satellite orbit determination. The position error of overlapped orbit differences for combining is less than that for ranging only. The residual of predicted orbit forward 5.5 days for combining is 3.1762 m, while the residual for ranging only with the same duration is 3.5380 m. Both the orbital overlapping and orbit prediction experimentations can testify the constraint in the transverse direction of satellite orbit with differenced ranges, and the results show that the accuracy of orbit determination and orbit prediction is improved by combining differenced ranges and C-band ranging.YANG Ying YANG XuHai LI ZhiGang FENG ChuGang 2013Chinese Science Bulletin2013,58,19:1
