Loran-C Prediction Problems

Abstract

Control of time and frequency at remote stations and the maintenance of a constant time scale for Loran-C chains are problems of practical Importance. The stability of stations monitoring a Loran-C chain is analyzed - in particular, those stations monitoring the Northwest Pacific chain (LC/9970). Part of the analysis consists of comparing individual determinations of the quantity, U. S. Naval Observatory Master Clock (USNO MC) - LC/9970, with an averaged value and in making intercomparisons of monitored data.
