Regular time transfers have been continued with the National Institute of Standards and Technology (NIST) in Boulder, Colorado, with the NRC in Ottawa, Canada, and with the AMC, the USNO Alternate Master Clock in Colorado Springs, Colorado. The current site, established in 1893, includes the DOD Master Clock and the nearly 150-year-old “Great Equatorial” telescope, shown above, which is still in everyday operational use collecting CRF data. Naval Observatory is the preeminent authority in the areas of timekeeping and celestial positional observing, determining and distributing the timing and astronomical.

U Naval Observatory Washington, DC 20392, USA Abstract: The U Naval Observatory (USNO) has provided timing for the Navy and the Department of Defense since 1830 and, in cooperation with other institutions, has also provided timing for the United States and the international community. Tried to snap a photo of it but the Secret Service officer at the entrance told me no photos The Master Clock timescale of the Observatory is based on an ensemble of cesium-beam frequency standards, hydrogen masers, and rubidium fountains.

The clock measurement noise is about 25 picoseconds (ps) rms, which is less than the variation of a cesium clock over an hour. Standard time within each time zone is an integral number of hours offset from a time scale called Coordinated Universal Time (abbreviated UTC), maintained by a large number of very precise "atomic clocks" at laboratories around the world, including the U Naval Observatory. The third one from the left at the top is a radio-controlled clock for reference. Design changes to the system include the use of a Kalman filter for phase and frequency estimates, decreasing the time interval between steers, and the redesign of control parameters.

The National Institute of Standards and Technology - Time and Frequency Division maintains the standard for frequency and time interval for the United States, provides official time to the United States, and carries out a broad program of research and service activities in time and frequency metrology. Time Dissemination at the USNO. The operational system is based upon switches and counters that compare each clock against each of three master clocks once per hour and store the data on multiple computers, each of which generates a timescale and is capable of controlling the master clocks. sport surge v2 Time Dissemination at the USNO.
