When satellite launch power there was only tens watts, so satellite navigation signals reach very faint during ground, with two satellite navigation of the Big Dipper
Exemplified by system signal, its minimum signal level is about -130dBm when the B3 frequency points signal of 1268.52MHz reaches earth surface.Should
Signal power equivalent to 100,000 kilometers at 30W the size of light that sends of light bulb.So defending, to lead receiver easily same by low-power
The influence of frequency radio frequency interference, therefore satellite navigation must possess certain anti-electromagnetic interference capability.But the prior art is only
For Beidou navigation equipment test mainly for the antijamming capability survey in system test, being seldom related to component rank
Examination.
The content of the invention
It is an object of the invention to provide a kind of Beidou satellite navigation equipment interference free performance to test system, above-mentioned to solve
The problem of being proposed in background technology.
To achieve the above object, the present invention provides following technical solution：A kind of Beidou satellite navigation equipment interference free performance
Test system, including base, on the base fixed setting be useful for the satellite-signal simulator in simulation satellite signal source, use
In the satellite signal processing unit for receiving satellite signal source and reflecting back the satellite signal source received, the satellite-signal
Simulator includes the signal source transmitter for simulation satellite signal source, and the periphery of the signal source transmitter is provided with first
Satellite signal receiver and the first satellite-signal transmitter, are provided with the satellite signal processing unit for receiving signal source
Second satellite signal receiver of transmitter and the first satellite signal source transmitter and for the second satellite signal receiver to be connect
The second satellite-signal transmitter that received satellite-signal transmitting is gone back.
Preferably, set on the base between the satellite-signal simulator and satellite signal processing unit
There is Electromagnetic Interference generator.
Preferably, the computer analyzed satellite-signal is provided with the base.
Preferably, the computer respectively with satellite-signal simulator, satellite signal processing unit and Electromagnetic Interference
Generator signal connects.
Preferably, the satellite-signal simulator and satellite signal processing unit are fixed at institute by mounting bracket
State on base.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the present invention is on base by setting satellite-signal simulator and satellite signal processing unit, during work, letter
Number source transmitter simulation satellite signal source sends signal to the second satellite signal receiver by Electromagnetic Interference generator, and
Two satellite signal receivers send the signal to the first satellite signal receiver by the second satellite-signal transmitter, and first defends
The signal is led to the first satellite-signal transmitter again and sent to the second satellite signal receiver by star signal receiver, then second is defended
Star signal receiver repeats the above process so that signal source is between satellite-signal simulator and satellite signal processing unit
Constantly circulation, so as to attenuation degree of the test signal in long range communication process.
2nd, the present invention can testing source anti-electromagnetic wave interference performance, have it is simple in structure, easy to use, use effect
The advantages that fruit is good.
