Overview

The VEXXIS GNSS-802 antenna has an innovative design featuring multi-point feeding network and radiation pattern optimization technology. Without forgoing the tracking performance, it is able to maintain a low profile while achieving both low gain roll-off from zenith to horizon and high peak zenith gain.

The GNSS-802 antenna is ideal for applications where the sky is partially visible, such as operating close to tree lines, under foliage or in urban canyons. This design comes with the ability to track low elevation satellites, while maintaining a high gain for higher elevation satellites. For an enhanced positioning solution, the antenna is able to track any visible satellites from horizon to zenith, providing the maximum number of observations.

The antenna has a weatherproof design with an IP67 rating and an MIL-STD-810G rating which means it’s able to sustain intense vibration.

The GNSS-802 antenna supports dual-frequency GPS (L1, L2), GLONASS (L1, L2), Galileo (E1), and BeiDou (B1). Superior multi-path signal rejection is ensured by GNSS-802 and has an enhanced performance in multipath environments. Through its novel design the antenna is also able to achieve greater phase center stability.

Low elevation angle tracking capabilities are enhanced by this new technology, as a result extending operation to the entire GNSS constellation. This directly translates into a better RTK solution and improved carrier phase measurement.
