Abstract:	This paper presents the results of laboratory tests of GPS receiver susceptibility to radiofrequency interference (RFI). The tests were performed at the U.S. Department of Transportation (DOT) Volpe National Transportation System Center (Volpe Center) Landing Systems Laboratory under the sponsorship of the Federal Aviation Administration (FAA). The overall objective of these tests was to ascertain the sus- ceptibility to interference of a variety of aviation-class GPS sets. Several RFI-related receiver phenomena were meas- ured: loss-of-lock (interference level at which receiver loses navigation capability); accuracy degradation in the presence of interference; and signal acquisition and reacquisition times in the presence of interference. Several types of interference were employed, as were a wide range of frequencies. Particular emphasis was placed on frequencies near Ll (1575.42 MHz), where receiver susceptibility is highest.
