摘要
介绍了GPS用于低轨道空间飞行器定轨的基本原理和数学模型;详细分析了GPS应用于低轨卫星定轨必须考虑的几项误差源,给出相应的计算模型;最后用所述方法进行Champ卫星定轨解算,验证了方法及模型的正确性,并对可能提高的定轨精度进行了分析.
The principle and mathematic model of orbit determination of LEO satellites using GPS are analyzed in this paper.Some special considerations are focused on the error modification and accuracy improvement.Numerical results are given by which the data of Champ satellite is analyzed.
