| Abstract: | 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. |
