The utility model provides an early warning platform for the interference of solar radio burst on a navigation system. The main reflection face of the existing solar radio telescope is used. A GPS satellite antenna is placed in an antenna main focus feed source. The antenna output accesses a one-out-three microwave switch. Three inputs of the microwave switch are respectively connected with a noise source, an antenna signal and a 50 ohm matching load. The output is connected with the input of a low noise amplifier. An amplifier output signal is connected with a filter group. The output of each filter is connected with a corresponding amplification module and a corresponding detection module. The output of the detection module is connected with a master control computer which controls eight-channel acquisition. The computer controls a switch controllable noise source which is placed in front of the low noise amplifier and a 50 ohm normal temperature load, A standard calibration system is established. According to the utility model, L band solar radio burst can be quickly detected, and warning information of possible influence is provided for the navigation system, and especially a Beidou system which is developed in China at present.
