NovAtel/VEXXIS GNSS-804


Manufacturer : 1 / Category : 3

The VEXXIS GNSS-800 series antennas feature a patented multi-point feeding network and radiation pattern optimization technology. In additional 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 gain roll-off from zenith to horizon without sacrificing tracking performance. This new technology significantly enhances the low-elevation angle tracking capabilities, extending operation to the entire GNSS constellation. Furthermore, the antenna is able to achieve greater phase center stability through our innovative element design. This directly translates into improved carrier phase measurement and a better RTK solution. 


Features

* Supports dual-frequency GPS, GLONASS, Galileo and BeiDou signals
* Multi-point antenna feed provides stable phase center and enhanced multipath rejection
* Radiation pattern optimization technology yields exceptional low elevation satellite tracking
* Provides exceptional tracking performance previously unachievable in a small form factor
* Hermetically sealed enclosure to endure the toughest environment
