Two-Satellite Navigation Using Loran and GPS

Leonard Kruczynski, Ralph Eschenbach

Abstract:	Previous papers have shown that LORAN and GPS form a mutually beneficial navigation system. LORAN can help GPS with initial position fixing and GPS can help LORAN by resolving ambiguities and cycle slips. We have also alluded to the fact that two satellites and one TD could be used to generate a position fix. In this paper we describe that technique as well as provide data showing the results of that capability. Using this technique, we can get up to 17 hours of position fixing in locations where only one TD is available. This allows for position fixes when neither GPS nor LORAN are capable of position fixes by themselves.
