VEXXIS GNSS-850
Antenna

The VEXXIS GNSS-850 antenna from NovAtel supports all GNSS constellations and frequencies and is rugged enough to withstand the toughest environments. The low-profile design, L-Band support, along with multiple path signal rejections makes it ideal for applications where the sky is partly visible.

Overview

The innovative design of the VEXXIS GNSS-850 antenna features multi-point feeding, which provides stable phase center and enhanced multipath signal rejection for enhanced performance in multipath environments. It supports all GNSS constellations and frequencies as well as L-Band signal reception.
 

The radiation pattern optimization technology in the GNSS-850 yields exceptional low elevation satellite tracking, while maintaining a high gain for higher elevation satellites. This results in better RTK solution and improved carrier phase measurement. This antenna is able to maintain a low profile while achieving both low gain roll-off from zenith to horizon and high peak zenith gain without forgoing the tracking performance.
 

The GNSS-850 is ideal for applications where the sky is partially visible, such as operating close to tree lines, under foliage or in urban canyons. For an enhanced positioning solution, the antenna is able to track any visible satellites from horizon to zenith, providing the maximum number of observations.
