Abstract This paper carried out different levels of combined simulations of COMPASS, GPS and GLONASS systems based on the STK software, and analyzed the data of the visible satellites number, PDOP value and the positioning accuracy in China region. Simulation results indicate that: with the given UERE value of the various systems in the Standard Positioning Service, the positioning accuracy of the combination of three systems is 56 m, and PDOP value is 0.8~0.9, which is better than the combination of dual systems, while the combination of dual systems is superior to the single system. Meanwhile, the results also show that the PDOP value in combination of three systems is lower and the positioning accuracy is higher, and the fluctuations are more gentle.
