USER GUIDE
OM-20000117
Rev 2
September 2013
The GPS-701-GGL and GPS-702-GGL are active antennas designed to receive signals from the GPS and
GLONASS satellites as well as L-Band signals.
The GPS-701-GGL is designed to operate in GPS L1 (1575.42 MHz), GLONASS L1 (1598 - 1611.5 MHz),
and L-band (1525 - 1565 MHz) frequencies. It also supports Galileo E1 frequency and the BeiDou B1
frequency.
The GPS-702-GGL is designed to operate in GPS L1 (1575.42 MHz), GPS L2 (1227.60 MHz), GLONASS
L1 (1598 - 1611.5 MHz), GLONASS L2 (1243 - 1255 MHz) and L-band (1525 - 1565 MHz) frequencies. It
also supports the Galileo E1 frequency and BeiDou B1 frequencies.
This guide provides the basic information you need to install and begin using your new antenna.
ADDITIONAL EQUIPMENT REQUIRED
The following equipment is required to set up the GPS-702-GGL or GPS-701-GGL 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
•
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.

Antenna Mount
The metal adapter on the bottom of the antenna is fixed in place. Do not attempt to remove it.
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.
2. Align the mount thread with the metal adapter on the bottom of the antenna and rotate the antenna
clockwise until it is securely screwed to the mount. Using a wrench, tighten the adapter to the mount.
3. Remove the dust cap from the antenna’s TNC connector.
4. Attach the male TNC connector of the coaxial cable to the antenna’s TNC connector.
5. Attach the other end of the coaxial cable to the antenna input port of the receiving device, which must
provide power as detailed in the SPECIFICATIONS section of this guide. All NovAtel GNSS receivers
provide the necessary power through their antenna RF connectors.
ANTENNA CARE
The GPS-701-GGL and GPS-702-GGL are designed to withstand the elements, including rain, snow, and
dust. However, to ensure your antenna performs optimally, keep the radome (the top surface of the
antenna) clean and brush off any ice and snow. In addition, ensure the TNC connector remains clean and
dry and replace the dust cap when a cable is not connected.
