Abstract

For the accuracy of highly kinematical positioning of GPS carrier phase is not easy to be obtained directly, a data processing method is presented based on the analysis of several common kinematical positioning accuracy analytical methods. The method firstly analyzes and models the state of motion carrier, and then conducts a statistics variable composed by multiple positioning data , Finally uses a determined relation between the variance of the statistics variable and the variance of the positioning error to gain the variance of positioning error by calculating the variance of the statistics variable. The test results show that the method is effective for random error characteristic analysis.
