Abstract：OpenGL is the premier environment for developing interactive 3D graphics applications, which is used widely in remote sensing, flight simulation, satellite orbit visualization and other fields. For users to understand directly the movement of current vehicles in real time in multiangle, multilevel ways, GNSS simulation software needs realtime 3D visualization of moving vehicles. The method how to use OpenGL to realize the flight simulation visualization and show the result according to output the of GNSS simulation such as pitch angle,yaw angle and speed is presented , which has a good visual effect.
