WWVB's Colorado location makes the signal weakest on the U.S. east coast, where urban density also produces considerable interference. In 2009, NIST raised the possibility of adding a second time code transmitter, on the east coast, to improve signal reception there and provide a certain amount of robustness to the overall system should weather or other causes render one transmitter site ...
Other early products included WWVB frequency and time standards which offered atomic clock accuracy at a fraction of the cost. This led to widespread use of these products in vital communications networks, such as two-way police radio simulcast systems, and master clocks for accurate time stamping of data and events within emergency call ...

Distributed temperature sensing systems (DTS) are optoelectronic devices which measure temperatures by means of optical fibres functioning as linear sensors. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. A high accuracy of temperature determination is achieved over great distances.
The American station WWVB is the only option for reliable time signals during geomagnetic storms in the Western Arctic, based on WWVB's published pattern maps. If WWVB is not available, those who need precision time transfer may be able to use GPS time transfer instead.
A modern LF radio-controlled clock. A radio clock or radio-controlled clock (RCC), and often colloquially (and incorrectly [1]) referred to as an "atomic clock", is a type of quartz clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.
When summer is in full swing and it’s time to switch on the air conditioning, you may find yourself in one of two camps: Complaining the thermostat setting is too cold, or uncomfortably warm ...
An atomic clock is a clock that measures time by monitoring the resonant frequency of atoms. It is based on atoms having different energy levels . Electron states in an atom are associated with different energy levels, and in transitions between such states they interact with a very specific frequency of electromagnetic radiation .
