The GPS satellite system consists of 32 satellites orbiting the earth. Each satellite has an atomic clock synchronized to UTC time and broadcasts this information – along with the position of satellite – on a radio signal. Our GPS Receiver converts this information into a serial data stream and sends it to our tower clock controller, which computes the offsets for your local time zone and corrects for daylight saving time if required.
Our GPS Receiver has to be located so it has a “RF transparent” view of the sky, so it can be mounted outdoors, or inside of “RF transparent” materials such as wood or plastic.
Note: “UTC” time is Coordinated Universal Time, or essentially Greenwich Mean Time (GMT).← Frequently Asked Questions
