摘要
给出了GPS伪距定位在动态模式下的改正模型 :对流层折射延迟、电离层延迟改正、地球自转改正、相对论效应改正、卫星天线和接收机天线改正、固体潮改正。并针对单频GPS接收机进行动态伪距定位的试验 ,分析了各项改正对GPS伪距定位的精度影响及综合改正后的精度分析。
In real-time mode, some kinds of error corrections for GPS pseudo-rang are given in the paper, i.e. tropospheric refraction delay, ionospheric refraction delay, earth-rotating correction, relativity effect, satellite antenna eccentricity, solid tide correction. Based on experiments of single frequency point positioning, each way of correction has been analysed in this paper. Finally,give out the accuracy of point positioning.
