Real-Time Validation for Satellite Navigation Signal Simulation System

Abstract:

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. This simulation system can also be used to validate the real satellite navigation signal system.
