This paper focuses on how to calculate GPS satellite orbit parameters through IGS data. Choosing a group of appropriate parameters, and the relationship between satellite position in ITRF and these parameters are founded, and these parameters can be estimated using some successive ephemerides. Three different methods are introduced detailedly.

本文以IGS精密星历为基础，深入研究了利用精密星历计算GPS卫星轨道参数的模型与方法，并对三种不同的计算方案进行了比较研究，其目的是寻找一种合适的计算方法，得到能够正确反映一个较长时间段内(如800天)轨道参数随时间变化的规律。
