Abstract:	In light of the September 2001 terrorist attacks and the Department of Transportation’s (DOT) Volpe Study on national vulnerabilities associated with overdependence on GPS, the importance of objectively assessing the capabilities of a modern Loran system has greatly increased. The Federal Aviation Administration (FAA) has an active program to investigate Loran as a complement to GPS, and the United States Coast Guard (USCG) is modernizing its Loran infrastructure. This paper reviews the development status and capabilities of a new H-field antenna and digital signal processing (DSP) – based Loran receiver system undergoing assessment by the FAA, and presents test results from side-by-side comparisons with GPS and legacy Loran receivers. Empirical results suggest Loran is a logical choice to become the national complement to GPS.
