GPS (global positioning system) clocks work on Satellite communication.
These clocks give us the appropriate time as it is connected to the satellite.
A GPS Master can integrate with 'N' no of clocks within a range of 400 mtrs.
The clock or SLAVE takes its signal from the master and displays the right time.
They work on 230V50Hz Power.
They can be connected to available UPS power so that power continuity can be available.
In times of loss of power, once restored they will indicate the appropriate time.
In times of loss of connectivity with satellite it will operate on RTC (Real time clock) where the accuracy level will be 2sec per 48hrs. this can happen in rainy season where there are heavy rains, clouds etc.
