Example Embodiment
[0022] The electromagnetic interference test between modules of Beidou equipment can be tested with the help of a full-wave anechoic chamber. The test system is such as figure 1 Shown. It mainly includes integrated test terminal, measurement antenna, two groups of communication antennas, Beidou satellite comprehensive tester (Beidou satellite signal source), interference source (mobile network simulator, etc.), turntable controller and full electric wave anechoic chamber. The integrated test terminal is used to control the test instrument and the tested user machine, analyze the test results, etc., the communication antenna is used to send and receive Beidou signals, and the other is used to send and receive signals from the interference module. The Beidou satellite signal source is used to simulate the Beidou satellite navigation signal , Simulate satellite orbit, atmospheric time delay error and user motion trajectory, build a simulation working environment of navigation recei...
