Design Of Uav Distributed Aided Navigation Simulation System Based On Scene/Terrain Matching

Aiming at the demand of UAV navigation when GPS fails, an integrated navigation simulation system based on scene/terrain matching is designed. The system supports a variety of matching algorithms or algorithm combinations to implement different inertial navigation correction models in complex terrain conditions. A distributed closed loop simulation platform is built to simulate the real flight environment to study the influence of different flight conditions and algorithms on navigation accuracy. The simulation results show that the system can effectively achieve the simulation requirement, which has a high practical application value.
