Abstract:

The first phase of the NAVELEXNRLUSNO 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.
