Design and Realization of Satellite Running-on-orbit Visualization Simulation System Based on OpenGL

According to the actual problem of building a satellite on-orbit-running visualization simulation platform,a satellite running visualization simulation system based on OpenGL technology is designed.The logic structure and network structure of the system is intro- duced.By the method of ADO technology,the accessing of satellite running database is realized,and by 3DS MAX technology,the satellite model and earth model are constructed.Finally,the visualizations of satellite on-orbit-running,overlay effect and communication route are achieved.The practices demonstrate that the system can simulate the whole process of satelliteon-orbit-running,and provide the assistant support platform of the real-time manage and decision for satellite.At the same time,the system provides the virtual training platform for network-training of aerospace army,and the system is valuable to build the virtual battlefidd simalation system under the condition of infor- mation.
