摘要
介绍了GPS星历参数及其算法研究的现状,分析了GPS星历参数的比例因子与星历参数设计需考虑的四种因素之间的联系,讨论了星历参数比例因子的计算过程,并使用模拟数据对其进行了验证。
The present research situation for GPS ephemeris parameters and their algorithms is firstly introduced in this paper. Then the relations between the scale factors for GPS ephemeris parameters and four factors needed during its design are analyzed. Finally the calculating process of the scale factors for GPS ephemeris parameters is discussed, and verified by the simulation data.
