UTC Dissemination to the Real-Time User: The Role of USNO

reportActive / Technical Report | Accession Number: ADA502461 | Open PDF

Abstract:

Coordinated Universal Time UTC is available worldwide via the Global Positioning System GPS. The UTC disseminated by GPS is referenced to the U.S. Naval Observatory Master Clock, UTCUSNO, which is regularly steered and maintained as close as possible to UTC 9 BIPM, the international time scale. This paper will describe the role of the USNO in monitoring the time disseminated by the GPS and the steps involved to ensure its accuracy to the user. The paper will also discuss the other sources of UTCUSNO and the process by which UTCUSNO is steered to UTCBIPM.
