Abstract
In multi-system compatibility and interoperability application, time offsets between different navigation systems is an important factor affecting the service performance. To verify the correctness and effectiveness of algorithm that how to deal with system time offsets in multi-mode receivers, GNSS navigation signals simulator is required the system time offset simulation function. The simulation algorithm and the effect on the navigation services performance of system time offsets were discussed. Firstly, the time offset parameters in navigation message and its physical meaning were described. Then, proposed a unified multi-GNSS system time offsets simulation method base on UTC and given system time offsets parameter simulation algorithm. Finally, according to different application scenarios, the impact on the performance of the navigation service availability of two system time offsets processing method-system level and user level-were analyzed and compared.
