Yes you can really avoid being late with the right clock.
Wall clock with gps.
The gps system is based on atomic clock technology.
Consequently the gps constellation can be considered a set of 24 orbiting gps clocks with worldwide 24 hour coverage.
This provides you the security of keeping everything within your local network and provides the accuracy of a stratum one time source.
The global positioning system more commonly known as gps is a satellite based navigation and positioning system.
Dedicated timing receivers can serve as local time standards with a precision better than 50 ns.
The current clock design allows a choice between 3 3 and 5 0 vdc to feed the gps antenna allowing the use of more common remote located gps antennas.
The cafepress line up of wall clocks is huge and ever growing delivering a large variety of unique decorative clocks for your home or office.
The gps clock provides everyone on earth with access to atomic time standards without needing a local atomic clock.
This particular clock uses 6 of the 1 alphanumeric displays with controllers to create a 6 character display.
The gps alphanumeric wall clock is measurably smaller in size compared to the last one but a lot more sophisticated with its knowledge of local time.
Gps time transfer accuracy is within 40 nanoseconds of utc.
My clocks are deep inside by house which has radiant barrier think of it a giant aluminum foil umbrella thermal insulation so i use a gps antenna located on my roof.
Theory behind the gps system began in the 1970 s and was created by the us department of defence with the need to acquire extremely accurate positioning information for global navigation.
Each gps satellite has multiple atomic clocks synchronized to a ground based master clock.
Gps galileo and glonass satellite navigation systems have one or more caesium rubidium or hydrogen maser atomic clocks on each satellite referenced to a clock or clocks on the ground.
If none of these are suitable options timemachines also offers gps time servers that provide an accurate reliable time source to the ntp wall clocks and your entire network.
While gps time itself is designed to be kept within one microsecond 1 µsec or one millionth of a second of utc excepting leap seconds the satellite clocks can be allowed to drift up to a millisecond 1 msec or one thousandth of a second from gps time.
The gps constellation consists of 24 orbiting satellites with each one containing a highly stable atomic cesium clock which is continuously monitored and corrected by the gps control segment.
Electronic clocks low.
