With the opening of the BDS-3 and the rapid development of 5G communication technology, China is committed to applying Beidou airborne equipment to civil aircraft and promoting the autonomy of civil aviation equipment. This paper uses the effective carrier-to-noise ratio to research the interference of the 5G signals coverage area on the airport ground to the downlink of Beidou RDSS signals and establishes an interference analysis model. Different RDSS receiver front-end filter bandwidths are selected to simulate the degree of interference between the two systems and analyze the relationship between RDSS receiver elevation angle and signal loss to determine the conditions in that mutual interference is generated between the systems. The results show that the appropriate width of receiver bandwidth can reduce the degree of interference from 5G signals to RDSS signals, and the elevation angle of the Beidou RDSS receiver is approximately 90°with minimal transmission loss when the RDSS signals are considered to the free space transmission.
