GPS MASTER

The Master Unit receives highly accurate Atomic time information from a network of GPS satellites to transmit the same at regular intervals to all Display Clocks within a range of 300m radius through Wireless Radio Frequency (RF) signals. Apart from receiving Time signals from the Master units via RF, all Display Clocks also have function to retransmit the Time signals via RF to other nearby clocks within a range of 300 m. Depending on the site layout, Area & Distance, the optimum number of Master & Clock units need to be decided to ensure full coverage.
