Experimental investigation of electromagnetic compatibility between GSM-900 cellular networks and REE of the aeronautical radionavigation service

The paper deals with a EMC problems between the GSM-900 general-purpose land mobile network and the radio electronic equipment (REE) of the aeronautical radionavigation service resulting from the national special features of the frequency allocations in Russia. Presented are the results of bench testing aimed at determination of the signal-to-interference ratio at the ARNS aircraft receiver input in the presence of unintended interference from GSM-900 network REE. The paper also describes the results of the flight test for evaluation of the ranges of interfering effects.
