Disclosed is an early warning platform for a solar radio burst disturbance incident in a navigation system. The early warning platform for the solar radio burst disturbance incident in the navigation system is characterized in that a main reflection face of an existing solar radio radiation telescope is used, a GPS (global position system) satellite antenna is placed on an antenna prime focus feed source, an antenna output end is connected with a one-out-of-three microwave switch, three input ends of the microwave switch are respectively connected with a noise source, an antenna signal and a 50 omega matching load, an output end of the microwave switch is connected with an input end of a low noise amplifier, an output signal of the low noise amplifier is connected with a filter group, an output end of each filter is connected with a corresponding amplification module and a corresponding demodulation module, output ends of the demodulation modules are connected with a main control computer which controls eight channels to collect, and simultaneously the main control computer controls a switch controlled noise source and a 50 omega normal temperature load, which are placed in front of the low noise amplifier, and furthermore a standard calibration system is built. The early warning platform for the solar radio burst disturbance incident in the navigation system can rapidly detect solar radio bursts of an L wave band, and provides alarm information to the navigation systems and especially Beidou systems energetically developed in our country when the navigation systems and especially the Beidou systems are possibly influenced.
