Abstract:Aimed at the restricted navigation module of unmanned aerial vehicle(UAV) ground control station(GCS), this paper designed a navigation electronic map based on Web Mercator. This module simplified the electronic map making by using ImageStone class library, and achieved the function of map plotting, translation, and zoom. On this basis, the paper completed route planning, real-time display of the route, saving the data and etc. The design of the navigation electronic map greatly increased the real-time display in the fusion of electronic map and navigation information. The test of UAV simulation system verified the rationality and availability of the design, the navigation electronic map can finish the navigation task efficiently and accurately.
