Several times a day, he sends a file to the bureau with the time he thinks it is, based on the cesium clock
at the National Institute of Standards and Technology in Boulder, Colo.
The result could be clocks that measure time in intervals thousands of times smaller than now possible with cesium clocks
, according to the Joint Institute for Laboratory Astrophysics (JILA), a partnership of the U.
The technology, including cesium clocks
, PTP grandmasters and Oscilloquartzs network management system, will be a critical component of Globe Telecoms national core network as it responds to demand for LTE services and other applications that require highly accurate frequency and phase information.
The new system uses laser cooling to increase the interaction time 100 to 1000 times greater than a conventional cesium clock
Oscilloquartz, an ADVA Optical Networking company, announced today that TDC has deployed its OSA 3230B cesium clock
in its national optical transport network.
Because the hydrogen maser is more stable than the cesium clock
over short periods of time, it is useful as a secondary time standard and for making high-precision frequency measurements.
Datum's Cesium clock
provides Stratum 1 timing synchronization, which enables us to improve the quality of calls traveling over ITXC.
Did you know that the timepiece he uses -- a cesium clock
-- is so accurate that it only loses or gains one second every 162,000 years?
With the launch of its low-cost SmartClock technology, which achieves accuracy similar to that of the cesium clock
, HP maintains its leadership in timing and positions itself to become the leader in communications timekeeping," said David W.
Next-generation clocks operate at optical frequencies, much higher than the microwave frequencies of cesium clocks
It makes cesium clocks
so accurate, they won't gain or lose a second in 100,000 years.
The Model 9552 oscillator continues Symmetricom's legacy in the GPS program beginning with our cesium clocks
for GPS blocks I, II, IIA and IIF," commented Peter Cash, director, Space, Defense & Avionics Group at Symmetricom.
This location has been active in design and development of high performance frequency and time products since 1974, including cesium clocks
for GPS satellites.
