摘要
本文从伪距定位模型出发,分析了定位精度与观测误差、卫星星历误差、卫星钟误差、电离层和对流层的延迟误差、定位模型线性化误差之间的关系。
Based on pseudorange positioning model, this paper analyses the relationship between positioning accuracy and observation error, ephemeris error, satellite clock biase, ionosphere and troposphere delay error, linearijation error of positioning model and discusses the methods of improving GPS positioning accuracy.
