A LORAN C PRECISION GUIDANCE SYSTEM

The United States Coast Guard is implementing a feasibility demonstration of LORAN C to perform precision guidance of ore carriers on the St. Marys River. A special four-station LORAN C chain has been erected to provide optimal hyperbolic LORAN C coverage for the 60-mile river channel. The required navigation accuracies are in the 25 to 50 feet range. This paper presents the results of a test where a preliminary configuration of this Precision Guidance System was evaluated in the Hampton, Virginia area using Raydist to monitor the system. The test demonstrates that with optimal filtering of the data and the addition of a real time grid calibration the required navigation accuracies can be achieved.
