Validation of a Time of Transmission Monitor Suite for Measurement of the Offset Between Loran-C Transmissions and UTC

Abstract

The U.S. Loran-C system is an integral part of the national infrastructure for the dessimination of precise time and time interval. In 1997 the U.S. Coast Guard Loran Support Unit located in Wildwood, New Jersey, developed a Time of Transmission Monitor (TOTM) suite. The TOTM suite will be used to measure the average daily offset between UTC and the time of transmission of a Loran-C station. Direct measurement of the time of transmission of the Loran-C signal with respect to UTC will allow the Coast Guard to more tightly couple the Loran-C system to UTC. This paper will discuss the effort, jointly undertaken by the U.S. Coast Guard and the U.S. Naval Observatory, to implement and validate the TOTM equipment suite.
