A hybrid aircraft navigation system has been developed using Loran-C signals for continuous position location information, with periodic position updates from the Navy Navigation Satellite System (NAVSAT) to improve the accuracy of the system. Laboratory tests and flight tests have demonstrated the performance of the NAVSAT/Loran-C hybrid system and have established high confidence levels in its ability to provide accurate position location information, and to obtain in-flight local Loran-C grid calibration. This automatic system uses a Loran-C receiver, a NAVSAT receiver, a small computer, and associated display units to provide real-time readout of latitude and longitude.
