This article mainly talks about the function and characteristics of the satellite signal simulator, briefly explains the main use scenarios of the satellite signal simulator in the market application, and expounds the professional advantage of the satellite signal simulator after the market input and the real satellite ephemeris, so as to facilitate users to have more knowledge of the satellite signal simulator, and select the guardian suitable for its own application scenario.Star signal.

The satellite signal simulator is a test equipment for simulating the satellite navigation signal trajectory. It can simulate real-time simulation of the satellite frequency signal, or manually set up the simulation of the satellite navigation signal in the required navigation environment, and apply it to the simulation of the satellite motion, the atmosphere, the vehicle, the signal characteristics and other effects.We propose a set of identical trajectories with satellite receivers in a moving platform environment.

The reason why satellite signal simulators can be widely applied to many platform system tests is mainly because the satellite signal simulator can simulate the satellite signals that are simulated with real satellites. At the same time, the module is used for all satellite receivers of the test platform, and the way to deal with the signal of the satellite signal simulator is exactly the same as that of the satellite signal, so that the satellite receiver can be operated artificially.According to the parameters of the test scenario, the simulated signal is simulated and the path is simulated.

The use of satellite signal simulator solves the problems of the randomness of the sky satellite signal and the influence of the external environment when the satellite receiver receives the satellite signals directly during the testing process, and the errors of the satellite navigation paths in different environments in real time.By comparison, when comparing the satellite signal simulator with the real satellite signal in the test, when the test environment is in the indoor laboratory and the signal enclosed factory building, the satellite receiver receives the real-time satellite signal through the link with the antenna, and generates the noise and the signal simultaneously by transmitting the satellite signal to the indoor room.It is too difficult for the satellite to complete the normal test.At this time, it is necessary to use the satellite signal simulator, without external environmental impact, no noise and interference, and so on, which can effectively solve the test under various test conditions.

That is to say, the satellite signal simulator can be used in both the field test and the laboratory simulation test environment. To solve the problem of multi receiver or navigation path test, it is necessary to carry out in a repeatable security laboratory condition under controlled harsh environment. It can be widely applied to domestic automobile, receiver, air detection and other manufacturers that need to receive satellite receiver signals.

The satellite signal simulator is currently pushing the SYN5203 GPS signal simulator. Now it has been applied to the market. Customers who need the satellite signal simulator can directly contact our business people.
