。To control the take-off, landing and flying of ultra-low altitude UAV remotely, navigation and control methods were studied with virtual reality technology. With the aid of Multigen Creator, we built 3-D model of UAV, generated terrain by DEM data, and studied drive technology. According to the parameters from GPS receiver and other sensors fixed on the UAV, the 3-D model and scenes were derived. Meanwhile, feed back signal was given to adjust the plane’s gesture to insure the plane to fly along the route. GIS technology was used to display the UAV trace in digital map. Virtual experiment shows the feasibility of navigation and control of ultra-low altitude UAV.
