1. Introduction
This document describes the principle of operation and installation instructions of the GXR-GPS GPS
family, which is a GPS module based on a Garmin GPS type GPS-35-HVS.
GXR-GPS is used with GeoSIG Instruments to provide the global coordinates of the GPS antenna and
accurate date and time to the Instruments. It’s very useful for having one or several interconnected
Instruments precisely synchronised.
a
GPS provides only UTC time at 0° Greenwich meridian without summer time adjustment.
GXR-GPS is provided in a box with a cable length to be defined at the time of order or provided by the
customer. Upto 70 m cable length is possible with the standard GXR-GPS, upto 1’000 m with the
optional GXR-GPS-485.
All instructions within this User Manual also apply to the GXR-GPS-485, whenever only GXR-GPS is
mentioned.
