Abstract : The electromagnetic compatibility among the proposed RTCA SC-117 next generation microwave landing guidance system (LGS) and several existing microwave landing guidance systems proposed as interim system candidates was analyzed. The signal format for LGS was developed by Special Committee 117 of the Radio Technical Commission for Aeronautics. The angle data localizer and glideslope portions of the systems were deployed in an FAA-predicted high density 1980 environment and the possibility of compatible operation was assessed with the assistance of a computer analysis. The compatibility among the systems' DME functions was nalyzed using frequency/distance considerations. The EMC between the landing guidance systems and other in-band domestic systems and between the LGS and a foreign microwave enroute guidance satellite system (DIOSCURES) were analyzed using frequency/distance considerations.
