Abstract

In the case that magnetic levitation (maglev) is required to enter the airport and GBAS VDB is used as a means of aircraft approach in the future, a reasonable layout between maglev line and GBAS VDB is sought. Take maglev vertical across the final approach path of an aircraft as an example. Based on the analysis of the practical measurement RFI data of maglev arc according to three working conditions of maximum power acceleration, maximum power deceleration and passing the test site at a constant speed, and considering the ground reflection of the maglev arc, the EMC of the maglev arc to the VDB signal is analyzed when the VDB is near the runway threshold and far from the runway threshold. The results show that the maximum radiation intensity range of maglev arc is from 56.20 to 57.76 dBμV/m. When the VDB antenna is close to the runway threshold, the protection ratio of the maglev arc to the VDB signal will not be less than 26 dB, unless the maglev is within 410 m from the runway threshold.
