| 摘 要： | 考虑到基于双星定位系统的近地卫星联合定轨待估参数的时间相关性，提出了1种基于样条参数模型与动力学模型相互融合的联合定轨节省参数建模新方法，并基于传统联合定轨算法进行了具体的改进算法设计。理论分析和仿真计算表明，与传统联合定轨方法相比，该方法减少了待估参数个数，提高了轨道表示精度，并且使估计结构更加稳定，估计精度也得到了一定程度的提高。

| Abstract: | Considering LEO's combined orbit determination to-be-estimating parameter time pertinency based on Bi-satellite Positioning System(BPS),this paper puts forward a new method of combined orbit determination reduce parameter modeling which syncretized spline model and dynamics model,and designs concrete improved algorithm.Theoretic analysis and simulation computation show that this method makes parameter estimation structure more steady,and can improve precision of combined orbit determination by decreasing am... |
