Time synchronization from Loran-C

摘要

Loran-C navigational transmissions, at a frequency of 100 kHz, can be used to provide clock synchronization over long distances to accuracies within ???????±1 ????????s. Results to date represent improvements as great as three magnitudes over other operational long-range radio systems. This article discusses the timing capabilities of Loran-C and illustrates the techniques that are used for the derivation of time and frequency.
