Research on dynamic positioning accuracy evaluation method of GPS/Beidou dual mode navigation receiver

摘要

In recent years, the GPS/Beidou dual-mode navigation receiver has been widely used, and the evaluation requirements for the dynamic performance of satellite navigation receivers are increasing. According to the application field of satellite navigation receiver, the satellite signal simulator is used to develop the test method for the dynamic positioning accuracy of the navigation receiver, and a set of evaluation tools is constructed. The tool can output statistical evaluation results of dynamic positioning accuracy after a single test. The statistical evaluation results include various forms such as mean, variance, and circular probability error. The test results show that the test method and evaluation tool can quickly and effectively complete the evaluation of dynamic positioning accuracy.
