During 1984 and 1985 the FAA conducted a series of LORAN-C Stability Test Program Flights throughout the contiguous United States (CONUS). The data recorded along each flight path provide indications of time difference (TD) variations with respect to geographic location as well as indications of LORAN-C coverage, based on signal-to-noise ratio (SNR) and other signal parameters. This paper addresses the archiving of the FAA flight data in a tractable database format and the utilization of the database in deriving a signal strength attenuation model. Averaged signal strength parameters are used to develop a 60-cell conductivity map for LORAN-C coverage within CONUS.
