【Abstract】 In order to analyze problems such as coverage percent of mission area and reliable communication between unmanned aerial vehicle(UAV) and ground control station, a method for simulation and validation based on STK was proposed. The condition should be satisfied in theory to achieve seamless coverage of the mission area by using UAV reconnaissance and communication system was analyzed. A method for down link calculation of UAV and the ground control station was proposed. STK simulation was used for validating the correctness of theoretical analysis. It shows that the simulation results can provide rational support for UAV reconnaissance and communication system demonstration, design and optimization. Also the simulation results can provide reference to route planning and deployment of the ground station.更多还原
