VEXXIS™ GNSS-804L Antenna
The NovAtel 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 technology significantly enhances the low-elevation angle tracking capabilities, extending operation to the entire GNSS constellation. The greater phase center stability directly translates into improved carrier phase measurement and a better RTK solution.
ABILITY TO TRACK IN CHALLENGING ENVIRONMENTS
The ability to track low elevation satellites while maintaining a high gain for higher elevation satellites makes the GNSS-804 an good choice for any applications where the sky is partially visible. The antenna is able to track any visible satellites from horizon to zenith, providing the maximum number of observations for an enhanced positioning solution.
TOUGH AND PRECISE
The GNSS-800 antennas are tough high-precision antennas. They feature ultra-durable watertight enclosures and can sustain intense vibration. They have an MIL-STD-810G rating.
