Abstract: Through the secondary development of Google Earth, flight training simulation system for visualization of realization, the system used B/S structure, the client browser using Google Earth, all the development on the server side. Mathematical model of aircraft was constructed; 3D modeling software SketchUp was used to establish a realistic fighter jets, missiles, high and low speed flame and other 3D model; the established 3D models was imported into Google Earth; by Microsoft VC ++ 6.0, the secondary development on Digital Earth was achieved, and the control of aircraft and other 3D models was realized; Matlab was used to verify the validity of the mathematical model. The result shows that the simulation system has good visual effects and interactive features, scalability of the system is to meet the diverse needs of the Air Force's technical and tactical training, with good practical significance and promotional value.
