Although the GPS has been created for positioning (i.e. defining the location), it can also be used for other purposes. In the received GPS signal, there is embedded information about the current time and date. This time is very accurate because it is determined according to atomic standards. It may be slow or fast by just one millionth of a second per month. For the proper operation, it is required to place the receiver in the location providing the "visibility" of the sky.

The advantages of the GPS synchronisation:

• provides precise time synchronisation from the GPS satellites based on atomic standards,
• does not require any configuration,
• does not require the Internet connection,
• operates in every location on the Earth,
• a LED signalling proper signal reception is embedded in the receiver.

To take advantage of the satellite time synchronisation, you should equip the clock with the optional GPS Receiver..
