Abstract

The use of Loran-C as the best backup system to Global Positioning System (GPS) was discussed. It was observed that Loran-C's potential benefits hinge upon the level of position accuracy actually realized as measured by the 2 drms error radius. A significant factor limiting the accuracy of Loran system was the spatial and temporal variation in the times of arrival (TOA) observed by the receiver. The simulation efforts have shown that the Loran system is capable of meeting the aviation and maritime accuracy requirements.
