The United States Naval Observatory was established in 1830
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. Navy and the U.S. Department of Defense. Established by the order of the Secretary of the Navy John Branch on 6 December 1830 as the Depot of Charts and Instruments, the Observatory rose from humble beginnings. Placed under the command of Lieutenant Louis M. Goldsborough, with an annual budget of $330, its primary function was the restoration, repair, and rating of navigational instruments. It was made into a national observatory in 1842 via a federal law and a Congressional appropriation of $25,000. Lieutenant James Melville Gilliss was put in charge of "obtaining the instruments needed and books." Read more
Naval Observatory Soon Will Track Time to 100 Trillionths of Second The ultra-precise timing technology that enables NAVSTAR Global Positioning Systems and high-speed Internet communication soon may resolve the measure of time to 100 trillionths of a second, according to the world's authority in time-keeping and celestial observation.

The U.S. Naval Observatory performs an essential scientific role for the United States, the Navy, and the US Department of Defence. Its mission includes determining the positions and motions of the Earth, Sun, Moon, planets, stars and other celestial objects, providing astronomical data; determining precise time; measuring the Earth's rotation; and maintaining the Master Clock for the United States. Observatory astronomers formulate the theories and conduct the relevant research necessary to improve these mission goals. This astronomical and timing data, essential for accurate navigation and the support of communications on Earth and in Space, is vital to the Navy and Department of Defence. It is also used extensively by other agencies of the government and the public at large.
