Tallysman VeroStar™ GNSS Precision Antennas

Tallysman VeroStar™ GNSS Precision Antennas are designed and manufactured for high-accuracy positioning while being robust and reliable. VSP6037L antennas provide high gain over the full GNSS spectrum, while the VSP6337L antennas provide high gain over selected frequency bands. These antennas feature low roll-off from zenith to the horizon, efficiently tracking the GNSS and L-band correction signals from low elevation angles. Additionally, these VeroStar antennas have an optimized axial ratio at all elevation angles for excellent multipath rejection, enabling accurate and precise code and phase tracking of GNSS and L-band correction signals. 

The robust, pre-filter, and high-IP3 LNA architecture minimizes de-sensing from high-level out-of-band signals, including 700MHz LTE, while keeping a noise figure of only 1.8dB. The housing design has an integrated rubber bumper that absorbs routine impacts and has passed various tests (water pressure, shock, drop, salt fog, altitude, and vibration) to ensure these antennas can survive the rigors of day-to-day field use. Tallysman VeroStar GNSS Precision Antennas are suitable for all embedded applications, such as deformation monitoring stations, land survey rovers, autonomous vehicle navigation, and marine navigation.
