The Astrometry Department of the U.S. Naval Observatory (USNO) is responsible for the determination of the positions and motions of stars and solar system objects and the establishment of celestial reference frames. Advanced equipment and methods, such as the Full-sky Astrometric Mapping Explorer (FAME) spacecraft, large scale CCD measuring devices, speckle and radio interferometry, are being used or developed to extend the accuracy and brightness limits of the reference frames. The results of the observational programs are published in the Naval Observatory Publications and in refereed journals. This work is done in cooperation with the United States Navy, the Department of Defense, other United States agencies, organizations in other countries and the International Astronomical Union.
