This paper presents an analytical technique for evaluating the reliability of the LORAN-C system over the conterminous United States CONUS. Emphasis is placed on the technique itself and not the specific reliability statistics. The technique is applicable to the analysis of the existing USCG ground station configuration, as well as any proposed full-CONUS coverage station configuration. The technique is based on the use of a Markov Chain model to provide a probabilistic measure of system unreliability and incorporates signal strength, relative geometry, and receiver configuration which define system coverage. A simplified analytic procedure is employed to bound the system unreliability and a numerical example is presented based on preliminary LORAN-C station reliability statistics for solid-state ground stations and a simple receiver model.
