摘要
User range error (URE) is widely used to measure the effects of satellite orbit error and clock error on user positioning. A detailed calculation method of URE was brought forward including the partitions of the ground coverage of the MEO satellites and the calculation methods of the projection parameters of URE. The different TIRE performance of multiple Satellite navigation system was analyzed. Simulation results show that the radial direction projection parameters are basically the same, but the horizontal direction projection parameters are different among GPS, Galileo and BDS. The higher the satellite orbit, the smaller the horizontal direction projection parameters.
