【Abstract】 In this paper, an integrated navigation system which included the Chinese BDS, the U.S. GPS, the Russian GLONASS and the EU’s GALILEO was applied to be simulated. The simulated data was used to compare the current single GPS system, the current integrated system, future complete integrated system in global area’s GDOP and navigation accuracy, and analysis the improvement of the integrated satellite navigation systems in GDOP and navigation accuracy.更多还原
