Analysis of GPS Single Frequency and Dynamic Precise Point Positioning Accurcy Using IGS Precise Products

介绍了GPS单双频动态精密单点定位的数学模型以及利用IGS精密产品进行单双频动态解算的算法流程。采用IGS实测数据进行了GPS单双频动态精密单点定位精度解算试验并从外符合的角度评估了其定位精度。试验结果表明:GPS单频动态定位精度在分米级,双频动态定位精度在厘米级。

This paper introduces the GPS single frequency dynamic mathemattcal model ot the precise point posit：orang and the usage of IGS precision for single and double frequency the algorithm for calculating the dynamic process. The IGS measured data is used for GPS single frequency dynamic precise point positioning accuracy calculating test and from the angle of the outside conform to evaluate its precision. The test results show that the single frequency GPS dynamic positio ning precision in the decimeter level, doublefrequency dynamic positioning accuracy level in cm.
