The satellite navigation signal simulation system is a frequency signal one, which simulates the signal of high precision and consisted of diverse information. Firstly, the satellite navigation signal simulation system is introduced; it takes on three characteristics, comparing to generic simulation system. Secondly, several dements such as simulation steptime, time function and network data transfers, which affected real-time quality of simulation system are analyzed. Finally, four real-time quality indexes such as frame overflow, time synchronization etc are validated in detail. By analyzing and validating, the result shows that the simulation system possessing higher real-time quality and it can meet the requirement of real-time simulation for the system.
