The Simulation technology of OTV based on HLA was researched in this essay. Based on the technology, a distributed visual simulation system is established on the basis of HLA and STK, in which the space orbit transferring vehicle can fly around the low-orbit target, while hovering under the high-orbit target.

For a gas station training simulation system, the real time and reality of scene directly affect the application of system. In order to solve this problem, we used 3D virtual scene building technology based on OpenSceneGraph (OSG) to build gas station scene. Technology of levels of detail (LOD) was used to improve the real-time ability of the system during entity modeling. And then based on 3D entity model library and information files in Extensible Markup Language (XML), we built the parametric library and set up the gas station scene, which provided function information and attribute information. Experimental results show that the scene of virtual gas station can not only greatly improve the reality and immersion of system, but also well support the real-time simulation. Now, 3D virtual scene building technology based on OSG has applied successfully in gas station training simulation system, which provides feasible evidence for engineering simulation to solve practical problems.

The satellite navigation signal system is so useful that it can provide autonomous geo-spatial positioning with global coverage. The satellite navigation signal simulation system possesses the traits of large scale, complex structure and various model types, and the real-time performance of the simulation system is exigent. The simulation real-time performance index will be analyzed and tested roundly. Firstly, the framework of the satellite navigation signal simulation system is introduced. Secondly, several index such as simulation step-time, time function and network data transfers, which can affect the real-time performance of the simulation system, are analyzed. Finally, four real-time performance indexes such as frame overflow, the definition of frame synchronization and time synchronization, the precision of time synchronization etc, are tested and validated in detail. By analysis and test, the result shows that this simulation system possessing higher real-time performance and it can meet the real-time simulation requirement of the simulation system.

It had not been explored which real-time magnitude can meet the requirement of the simulation object in computer simulation system. Taking time delay into consideration, the influence of time delay on the stability of the low-altitude and low-speed small Unmanned Aircraft Systems (UAS) flight control system had been analyzed and the real-time magnitude of the miniature hardware-in-loop (HIL) simulation system was determined. Then a miniature HIL simulation system of the UAS flight control system was designed to prove the real-time magnitude feasibility. The result shows the real-time magnitude by time delay analysis can meet the requirements of flight control system.
