3 Mounting GPS antenna
The GPS satellite time receiver has been designed to provide extremely precise time. High
precision available 24 hours a day around the whole world is the main feature of the new system
which receives its information from the satellites of the Global Positioning System. The Global
Positioning System (GPS) is a satellite-based radio-positioning, navigation, and time-transfer
system. The source of time is based on real cesium atomic clocks. Time is represented as UTC
(GMT).
GPS worldwide time propagation
The GPS satellites are not stationary but circle round the globe in a period of about 12 hours.
They can only be received if there is no building in the line-of-sight from the antenna to the
satellite, so the antenna unit must be installed in a location from which as much of the sky as
possible can be seen.
