Novatel GPS-701-GGL, GPS-702-GGL User Manual
GPS-701-GGL and GPS-702-GGL
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. Both antennas are designed to
operate in GPS L1 (1575.42 MHz), GLONASS L1 (1598 - 1611.5
MHz), and L-band (1525 - 1565 MHz) frequencies. The GPS702-GGL is also designed to operate in GPS L2 (1227.60 MHz)
and GLONASS L2 (1243 - 1255 MHz) 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 GPS 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
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 GPS 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.

Height = Vertical phase center offset from antenna reference
point or antenna reference plane (ARP)
Only integer hardware revisions affect the phase center offsets. For
example, the numbers given for hardware revision 2.02 are applicable to an antenna labelled H/W Rev: 2.00, 2.04, 2.12 and so on.
Table 2 shows typical absolute and relative offset numbers for
the current GPS-702-GGL antenna model.
