Abstract: For the purpose of testing the performance of GPS(global positioning system) receivers, a GPS signal simulator is needed that can emulate the real GPS signals under all kinds of conditions. The high dynamic multi-channel GPS signal simulator device consists of hardware, computer and software. The software comprises the satellite navigation parameters calculation module, the target trajectory calculation module, the error calculation module and etc.Producing functional module of navigation data is a key technique that the high dynamic GPS signal simulator must solve. The physical meaning of the three parameters of satellite’s clock and the production model of the ephemeris were given. According to these parameters and their corresponding time parameters, Navigation data could be produced. By the procedure simulating and validating it with the navigation data, the results show that ephemeris and almanac correspond to the rules of the satellite’s arrangement.-
