Quick Links
The GPS-703-GGG and GPS-703-GGG-N are active antennas designed to operate at the GPS L1
frequency at 1575.42 MHz, the GPS L2 frequency at 1227.60 MHz, the GPS L5 frequency at 1176.5 MHz,
the GLONASS L1 frequencies from 1593 MHz to 1609 MHz, and the GLONASS L2 frequencies from 1238
MHz to 1254 MHz. The Galileo E5a, E5b, and E1 frequencies; BeiDou B1 and B2 frequencies and
GLONASS L3 frequencies are also supported. This guide provides the basic information you need to
install and begin using your new antenna.
ADDITIONAL EQUIPMENT REQUIRED
The equipment listed below is required to set up a GPS-703-GGG or GPS-703-GGG-N antenna:
•
A mount, such as a range pole, tribrach, or tripod, with a 5/8" x 11 thread that extends between 3/8" and
7/8" (9 mm and 22 mm)
•
A 1" open-end wrench
•
Coaxial cable with a male TNC connector (N-Type connector for the GPS-703-GGG-N)
•
A device with an antenna input port that both receives the RF signal and provides 4.5 - 18.0 VDC to the
antenna. (All NovAtel GNSS receivers provide the necessary power through their antenna RF
connectors.)
SITE SELECTION GUIDELINES
Before installing the antenna, select a site that as closely as possible meets the following conditions for
optimal performance:
•
An unobstructed line-of-sight from horizon to horizon and at all bearings and elevation angles.
•
As far as possible from reflective objects, especially those that are above the antenna and any water
bodies, which can be a strong source of multipath reflections.
•
If obstructions and reflective surfaces are within 30 m, ensure the site is as high as possible. Otherwise,
mount the antenna as low as possible.
INSTALLING THE ANTENNA
After a site has been selected, install the antenna as follows.
1. Verify that the thread on the mount does not extend more than 7/8" (22 mm) to ensure the plastic
inside the antenna receptacle is not damaged when the mount is inserted. If it extends further than 7/8"
(22 mm), add two jam nuts to shorten the exposed thread, ensuring the nuts are well-tightened.
