Establishment as an Optical Equipment DepotĮstablished by order of the United States Secretary of the Navy John Branch on 06 December 1830 as the Depot of Charts and Instruments, the Observatory rose from humble beginnings: Placed under the command of Lieutenant Louis M. He spent many nights at the observatory, watching and charting the stars, which had always been one of Adams’ interests. The names “National Observatory” and “Naval Observatory” were both used for 10 years, until a ruling was passed to officially use the latter.Īdams had made protracted efforts to bring astronomy to a national level at that time. ![]() President John Quincy Adams, who in 1825 signed the bill for the creation of a national observatory just before leaving presidential office, had intended for it to be called the National Observatory. ![]() Brief History Early Presidential Astronomical Interest The USNO performs radio VLBI-based positions of quasars for astrometry and geodesy with numerous global collaborators (IERS), in order to produce Earth orientation parameters and to realize the celestial reference system (ICRF).Īside from its scientific mission, a house located within the Naval Observatory campus serves as the official residence of the vice president of the United States. ![]() Winkler initiated the “Master Clock” service that the USNO still operates, and which provides precise time to the GPS satellite constellation run by the United States Space Force. It is one of the pre-1900 astronomical observatories located in an urban area at the time of its construction, it was far from the light pollution thrown off by the (then-smaller) city centre.įormer USNO director Gernot M. The observatory is located in Northwest Washington, D.C. Aside from its scientific mission, since 1974, the Observatory is the official residence of the Vice President of the United States.The Seal of the USNO with a quote from the Astronomica by Marcus Manilius, Adde gubernandi studium: Pervenit in astra, et pontum caelo conjunxit Air Force and it performs radio VLBI-based positions of quasars with numerous global collaborators, in order to produce Earth Orientation parameters. USNO also has an "Alternate Master Clock" site in Colorado Springs, CO which, with the "Master Clock", provides precise time to the GPS satellite constellation run by the U.S. Navy's higher elevation United States Naval Observatory, Flagstaff Station (NOFS) near Flagstaff, Arizona. Today, the observatory's primary observational work is done at the U.S. Located in Northwest Washington, D.C., it is one of the pre-1900 astronomical observatories located in an urban area at the time of its construction, it was far from the light pollution thrown off by the (then-smaller) city center. The United States Naval Observatory (USNO) is one of the oldest scientific agencies in the United States, with a primary mission to produce Positioning, Navigation, and Timing (PNT) for the U.S. ![]()
