摘　　要：研究概括了在不同的实验条件下利用GPS伪距获得较高精度定位结果的方法。实验结果的精度表明,这些方法的定位结果都能比常规的GPS伪距定位法的结果精度高,而且定位效果稳定。同时该方法也可为后续高精度定位及定轨等研究工作打好基础。The methods of high precise positioning using GPS Pseudo-range in different experiment conditions are discussed and concluded in this paper. The experiment results with real measurements show that these methods can get higher and steady accuracy than the common positioning method. And these methods can also pave a better road for the higher accuracy positioning and orbit determination which can be studied someday in the future.
