Radio controlled clocks
receive
wireless time codes and synchronize to the
Coordinated Universal
Time (UTC) within a fraction of a second.
This technology has
been extended to a wide variety of desk
clocks, wall
clocks and wrist watches that
synchronize to radio stations
such as WWVB, NIST and similar stations in
other countries.
The guaranteed precision in time is the
distinguishing
feature of a radio controlled clock, and is
also the reason why a radio controlled
clock
commands an edge over the conventional
clock.
Though radio controlled clocks have been
present
ever since the existence of radio, the
technology
was much expensive then. Advancement in
technology
and low costs of production has made the
purchase
of a radio controlled clock an affordable
one.
Though some believe that the radio
controlled
clock and an atomic clock are one and
the
same, here is the reason why the two are
different:
-
The radio controlled
clock receives the signals from a place
which has an atomic clock. The radio
controlled
clocks have a radio inside.
-
Atomic clocks have an
atomic oscillator inside. Such
oscillators
are usually cesium or rubidium
oscillators.
-
The radio controlled
clocks decode the signals received from
the radio station and synchronizes the
time
accordingly.
-
Keep clocks away from
computers, minimum distance being 1-2
meters.
-
Replace batteries as
and when necessary
-
Place the clock in
the
direction facing the radio station
-
Metal shielding can
interfere with the functioning of the
clock
- You can check the timings of your clock
vis a vis the radio station through the net
or by listening to the radio station.
