The framework and network structure of the simulation system are designed. The pivotal technology problems in the design, including 3D-terrain modeling, data transform of spaceflight and the time synchronization of real-time simulation, are discussed. After system assembly, the real-time visualization of the entire course in aerospace launch is realized. Through the verification in satellite launch, the result of simulation demonstrates that the visualization simulation system can real-timely process trajectory data in aerospace launch, and fleetly display the result of disposal. Compared with the traditional simulation system built on VC＋＋, Vega and OpenGL, the simulation system has the merits of little program work, transplant model simply, code authorization and debugging sententiously, etc, and can meet the demands of superintendence and decision in aerospace launch, which has the guidance significance and application value to the visualization of exploration moon engineering.
