GPS-703-GGG and

GPS-703-GGG-N

GM-14915086 Rev 4 April 2014

USER GUIDE

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.

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 connector.

4. Attach the male TNC connector of the coaxial cable to the antenna’s TNC connector.

For the GPS-703-GGG-N, attach the male N-Type connector of the coaxial cable to the antenna’s

N-Type connector.

5. Attach the other end of the coaxial cable to the antenna input port of the receiving device.

The receiving device 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-703-GGG and GPS-703-GGG-N 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 connector remains clean and dry

and replace the dust cap when a cable is not connected.



The metal adapter on the bottom of the antenna is fixed in place. Do not attempt to remove it.
