Abstract:Beidou lacks effective methods of navigation performance assessment in its representative applying scenes. This paper puts forward a way to evaluate the performance of Beidou user terminals based on the modeling of the scenes. This paper analyzes the possible challenge environment that Beidou might face and lists the elements to construct it. Then, the hilly scene is built following the steps. On this condition, the visibility of satellites and the precision of navigation are listed as major parameters to evaluate the navigation performance of user terminals. In the end, we construct a specific scene based on DEM and analyze the parameters mentioned above. The research demonstrates that the scene we have constructed can show the navigation performance in real life. The navigation performance assessment is practical in these circumstances.
