Remote GPS Receiver Requirements
Chapter 4: Hardware Installation
Remote GPS Receiver Requirements
The antenna must be mounted high enough to clear the peak of the MTS site roof. For systems in the
northern hemisphere, the remote GPS receiver should be mounted so that a clear view of the southern sky
is maintained. For systems in the southern hemisphere, the remote GPS receiver should be mounted so
that a clear view of the northern sky is maintained. The recommendation is to have view to the entire
sky if possible (10º above the horizon in all directions without any obstructions).
Isolate the remote GPS receiver from RF interference by mounting the antenna at least 3.7 m
(12 in.) horizontally from other transmitting antennas. For mounting and physical installation,
see instructions enclosed with the external GPS receiver head.
Remote GPS Receiver Cabling
The remote GPS (RGPS) receiver is connected to the junction panel using one of the three standardized cables
or a customer provided alternative. Standardized cables are terminated with a Deutsch connector (remote
GPS receiver site) and a metal shell 15-pin SubD connector (MTS site). The cable is supplied with an
additional SubD connector insert to allow the cable to be shortened and re- terminated where required.
The RGPS receiver cable has to be a shielded cable. The screen has to be grounded through the
metal shell of the D type connector. However, it is required for the cable screen to be connected
also to the site ground where the cable enters the building. This is similar to the grounding that
is applied to the RF cables. Please refer to R56 Guidelines and National Standards.
