Example Embodiment
[0041] The invention realizes the device of the high-dynamic satellite navigation signal source simulator. Under the action of the control module, at each rising edge of the control clock, the current satellite parameter state is calculated, loaded into the satellite signal generation module, and the navigation is received regularly Receiver positioning data processing. In the embodiment, the control clock is 1ms, and the interval for receiving the positioning data of the navigation receiver is 20ms. Considering the scale of the actual system, the maximum number of satellites simulated by the simulator is 20. If the currently visible satellite exceeds 20, select the satellite with a larger elevation angle for simulation.
[0042] The high dynamic multi-mode satellite navigation signal source simulation device includes the following steps:
[0043] 1) The control module reads the user's working parameters of the simulator. The working parameters include: receiver type parameters, r...
