摘要
本文利用模拟观测资料,估计了中国卫星跟踪网对近地测地卫星定轨和测定一些跟踪站地心坐标所能达到的精度。同时分析了近地卫星定轨的主要误差源,如大气模型、地球引力场模型的不确定性和跟踪网站坐标的误差等所产生的影响。
Using the simulated observational data, We have estimated the possible accuracies in determining low-altitude geodetic satellite's orbit and the geocentric coordinates of some tracking stations by Chinese network. In this paper, We have also gained an insight into main e'rrors affecting the orbit determination of the satellite, such as the shift of the tracking station coordinates, the unreality of atmospheric models as well as the gravity field models.
