摘要
针对高度在250～350km的三颗低轨道卫星，根据我国现有的卫星跟踪网和跟踪技术（雷达测距和多普勒测速）等观测条件，利用模拟方法估计和分析了各种误差源对定轨精度的影响，并对可能达到的定轨精度进行了恰如其分的估计。
For three low earth orbit satellites with altitude 250~350km, the accuracy of orbit determination, which can be reached using the radar ranging and Doppler data of Chinese satellite tracking network, has been appropriately estimated, and the effects of various error sources on the accuracy of orbit determination have also been analysed.
