摘要
研究空间飞行器问题,在星座条件下,观测数据较多,使用尽可能简单的几何定位方法来得到较好的定位效果,为提高探测卫星数据和定位的精度,采用一种基于视线观测的几何定位方法,将靶场试验雷达的双站交汇定位方法运用于天基观测系统,做了比较详细的精度分析,取得了较好的定位结果。考虑了几何构型和卫星数量的情形下的仿真实验结果表明:和最小二乘方法相比,采用的方法具有同样计算精度而计算效率更高;最后给出了低轨卫星和目标的空间几何构型对定位精度的影响分析结果。
Satellites constellation can obtain many observation data,for better location performance of location method as simple as possible,a kind geometry localization method based on the line of sight（LOS） observation has been studied,and the corresponding detailed precision analysis has been made.A nice result has been obtained by applying the two-spot intersect location method of range test radar to space-based observation system.The simulation considering geometric configuration and numbers of satellite show that this method has higher efficiency while has the same precision.At last,an analysis result is given to show how geometric configuration effects location precision.
