| 摘 要： | 提出了ＧＰＳ测量误差模型，并在此基础上第一次给出了伪距差分ＧＰＳ的ＲＭＳ误差表达式。这个误差表达式揭示了影响伪距差分ＧＰＳ定位精度的误差源及其影响大小。分析表明，不同于ＧＰＳ直接定位，伪距测量随机误差已是伪距差分ＣＰＳ的主要误差源之一。

| Abstract: | Differential GPS(DGPS)is a functional way to eliminate SA effection and erase shared errors between reference receiver and user receiver for improving GPS positionign accuracy .In this paper ,aGPS error model is given.And RMS error formula of Pseudorang Differential GPS(PDGPS)is providedfirst time in this paper.This formula disclose the error sources of PDGPS .The result shows that the pseudorang measurement random random error is the main dilution of PDGPS accuracy. |
