    Abstract
  • In order to analyze the navigation performance of BeiDou Navigation Satellite System (BDS) at airports in China,the BDS constellation is established by use of the Satellite Simulation Toolkit (STK),and the number of visible satellites and the geometry dilution of precision (GDOP) at 11 typical airports are simulated and analyzed.The simulation results show that there are more visible satellites and lower GDOP values for the BDS at most typical airports. By comparing the results with the table the GDOP values correspond to the positioning accuracy classification,it can be concluded that the BDS can provide superior navigation services at most typical airports in China,and the good technical support for the implementation of approach can be provided with the BDS.
