GNSS-850
Cutting-edge antenna technology
with superior tracking performance
Innovative design with multiple patents

Features

The VEXXIS GNSS-800 series antennas feature a patented multi-point feeding
network and radiation pattern optimisation technology. In addition to having
enhanced performance in multipath environments, the GNSS-850 antenna is able
to maintain a low profile while achieving both high peak zenith gain and low gainroll-off from zenith to horizon, without sacrificing tracking performance. This newtechnology significantly enhances the low elevation angle tracking capabilities,
extending operation to the entire GNSS constellation. Furthermore, the antenna
is able to achieve greater phase centre stability through our innovative element
design. This directly translates into improved carrier phase measurement and abetter RTK solution.

Tracking in challenging environments
The ability to track low elevation satellites while maintaining a high gain for higher• Supports all GNSS constellations andfrequencies• L-Band capable, supporting
correction services such as TerraStar• Multi-point antenna feed provides
stable phase centre and enhanced
multipath rejection• Radiation pattern optimisation
technology yields exceptional lowelevation satellite tracking

elevation satellites makes the GNSS-850 an excellent choice for any applications
where the sky is partially visible, such as operating close to tree lines, under foliage,• Provides exceptional tracking

or in urban canyons. The antenna is able to track any visible satellites from horizon

performance previously unachievableto zenith, providing maximum number of observations for an enhanced positioning

in a small form factor

solution.

Toughest precision antenna from Hexagon | NovAtel
GNSS-800 antennas are the toughest high-precision antennas NovAtel has
designed to date, ensuring their survivability even in the harshest operatingenvironments. The antennas feature ultra-durable watertight enclosures and havebeen proven to sustain intense vibration, earning the MIL-STD-810G rating.

• Hermetically-sealed enclosure toendure the toughest environments
