GNSS-804 Product Sheet

GNSS-804
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-804 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 new• Supports GPS, GLONASS, Galileo andBeiDou signal reception• Multi-point antenna feed provides

technology significantly enhances the low elevation angle tracking capabilities,

stable phase centre and enhanced

extending operation to the entire GNSS constellation. Furthermore, the antenna

multipath rejection

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• Radiation pattern optimisation
technology yields exceptional lowelevation satellite tracking• Provides exceptional tracking

The ability to track low elevation satellites while maintaining a high gain for higher

performance previously unachievableelevation satellites makes the GNSS-804 an excellent choice for any applications

in a small form factor

where the sky is partially visible, such as operating close to tree lines, underfoliage, or in urban canyons. The antenna is able to track any visible satellites from
