GNSS Products

Modern GNSS signals have much wider bandwidth than L1 GPS; plus greater precision is required. Tallysman’s Accutenna® technology responds to this need with an accurately tuned, wider bandwidth, dual feed patch element providing higher fidelity reception that yields improved multipath rejection and better output phase linearity.

Accutenna® technology antennas are available for reception of GPS and GLONASS, and wider band antennas are available for reception of Galileo, BeiDou, GPS and GLONASS constellations.

Tallysman has recently introduced its latest patented technology: VeraPhase® technology. This technology has proven its ability to provide very low axial ratios (horizon to horizon), very tight PCV, and excellent PCO repeatability. In short, the VeraPhase line of antennas match and often surpass the performance of traditional choke ring antennas making them ideal for all high performance applications including monitoring stations and RTK / PPP reference stations.

When using an adhesive mounted antenna, we recommend you familiarize yourself with the proper application technique.

Tallysman offers one of the widest ranges of GPS / GNSS antennas, and, in the antennas cataloged below, most likely has an antenna to fit the most demanding of applications.

Accutenna® antennas appear in red below.
