The Positioning Performance Simulation Analysis of BeiDou-2 and GPS in the Arctic Region

In order to master the positioning performance of BeiDou-2 and GPS in the Arctic region, the “5 GEO+5 IGSO+ 4 MEO” BeiDou-2 and “24 MEO” GPS using STK software is simulated. Based on this simulation, the satellite visibility, GDOP value and navigation accuracy in the Arctic region such as Yellow River Station (78.92° N and 11.93 ° E), Rick station (64.15°N, 21.57°W) and a third station are systematically analyzed. The results show that BeiDou-2 could not provide continuous and reliable service in the Arctic, while GPS has better performance.
