GPS DESCRIPTION
This section provides a description of the Global Positioning System (GPS) - Optional.
The third-party GPS antenna is a rugged, self-contained GPS receiver and antenna that receives a
universal GPS satellite clock signal. The GPS is an optional unit that connects to the BSDU. The GPS
synchronizes (based on frequency hopping) multiple Base Stations, ensuring that the entire AsMAX
network operates with the same clock based on a universal satellite clock signal. This is crucial in
eliminating radio frequency ghosting effects.
