Sole Means Navigation and Integrity Through Hybrid Loran-C and Navstar GPS

Frank van Graas

Abstract:	A minimum of four GPS range measurements or two LORAN-C Time Differences (TDs) are normally required for a position solution for enroute navigation, area navigation, and non-precision approaches. This paper describes a new technique that hybridizes GPS and LORAN-C used in the pseudorange mode to process efficiently all available navigation information, Emphasis is placed on combined GPS and LORAN-C timing, both for the ground/space facilities and the user. The hybrid system has the potential to solve the GPS and LORAN-C integrity problems; more range measurements are available than required for the navigation solution.
