Design of simulation platform for vehicle launching system erecting based on the Vega

Horizontal collimation is the development tendency of the vehicle launching system erecting. This paper sets the model of the whole erecting process of vehicle launching system and establishes the simulation platform, which imitates the whole erect process before erecting by 3D Visual Simulation Technique, and realizes the man-machine interaction function at the same time. Then develops the Vega thread in Virtual C++ environment, using Vega API drives vehicle launching model. For this, the platform makes it true that it can describe the calculation accuracy with different navigation mode intuitive and in real time, which provides analysis results for its application and extension, plan making, and precision evaluation.
