Overview

The VEXXIS GNSS-802L antenna comes has cutting-edge technology with results in superior tracking performance. Its innovative design comes features multi-point feeding network and radiation pattern optimization technology. It 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-802L 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 GNSS-802L antenna supports dual-frequency GPS (L1, L2), GLONASS (L1, L2), Galileo (E1), and BeiDou (B1). It also supports L-Band signal reception. Through its novel design the antenna is able to achieve superior multi-path signal rejection and greater phase center stability for enhanced performance in multipath environments.

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.

Features

  • Supports dual-frequency GPS and GLONASS plus Galileo and BeiDou
