Improved Master Clock Reference System at USNO (U.S. Naval Observatory),
Abstract
The first phase of the NAVELEX/NRL/USNO Master Clock (MC) upgrade program has been completed with the delivery of two VLG11B Hydrogen Masers to the U.S. Naval Observatory (USNO). After installation in a specially prepared Maser Laboratory with redundant environmental control, and a ten-day burn-in operation, the masers were independently tuned. Their subsequent performance caused a review of our plans for their operational use as part of the USNO MC complex. A revised concept is the basis for system integration presently in progress.
