We are one of the well distinguished companies in the market that is into presenting a quality approved range of gps master clock to our important customers.
Gps based wall clock.
Dedicated timing receivers can serve as local time standards with a precision better than 50 ns.
The gps system operates continuously round the clock of the year.
Advantages of gps based digital clocks.
This gps master clock is extensively acclaimed for its optimum performance and easy maintenance.
There will be one time in all the gps based clocks synchronized with the satellite time source.
The clocks have a unique feature whereby they use gps satellite signals to automatically configure themselves.
Why simple gps based clocks may be inaccurate in my original clock the microcontroller reads ascii data from the gps module and decodes the time information from that data.
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.
Offered range is manufactured by our deft professionals in accordance with.
This particular clock uses 6 of the 1 alphanumeric displays with controllers to create a 6 character display.
Consequently the gps constellation can be considered a set of 24 orbiting gps clocks with worldwide 24 hour coverage.
Simple easy to read style fits any decor 4 4 out of 5 stars 302 34 99.
Sharp atomic analog wall clock 12 silver brushed finish sets automatically battery operated easy to read easy to use.
Periodically the microcontroller s time is reset according to the gps information.
Gps clock synchronization electronic clocks control critical functions in many applications.
It takes time to read the gps data.
Indicator led to indicate receipt of gps time signal from the satellite.
Gps time transfer accuracy is within 40 nanoseconds of utc.
Once set the clocks never requires manual time adjustments.
The gps clock provides everyone on earth with access to atomic time standards without needing a local atomic clock.
Here is the problem.
The gps system is based on atomic clock technology.
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.
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.
There are 24 operational gps satellites orbiting the earth all are transmitting time signals.
Global positioning system gps based auto synchronous clocks have atomic clock accuracy without the need to ever program or set them.
