Survey and GPS Compasses

Tallysman’s Accutenna® and VeraPhase® technologies provide the phase linearity and tight Phase Center Variation (PCV) demanded in RTK / PPP systems, reference networks, and GNSS Compasses. Tallysman’s Accutenna® antennas are available in a range of enclosures, including embedded / OEM, compact magnetic mounts, and through hole mounted antennas.

Tallysman’s VeraPhase technology introduces patented technology which provides unparalleled Phase Centre Variation (PCV), PCV stability, low axial ratios from horizon to horizon across all frequencies, high gain element across all frequencies, and high efficiency within a light weight package.

  • More accurate positioning with Tallysman’s Accutenna® technology
  • Superior performance in urban canyons or high reflection environments since antennas provide superior multi-path rejection
  • Optional pre-filters to enhance out-of-band signal rejection (such as the 700 MHz band)
  • Antennas covering L1 and L2 signals for better accuracy
  • Antennas for use in Precise Point Positioning (PPP) Systems
  • IGS and NGS calibrated antennas
  • Embedded models for incorporation in your housing
  • Multi-constellation (GPS, GLONASS, Galileo, and BeiDou) coverage to maximize availability of satellite signals
  • Wide voltage range to work with virtually every receiver on the market
  • Strong electro-static discharge immunity
  • Rugged housings

Tallysman’s VeraPhase technology introduces new levels of performance to the survey world. It’s unparalleled low axial ratios from horizon to horizon across all frequencies, millimeter level PCV, high gain element, and high efficiency make it ideal replacement for choke ring antennas and other survey antennas.

Tallysman’s unique Accutenna technology provides low axial ratios and tight Phase Centre Variations (PCV) making them ideal for use in GNSS Compasses, RTK (both single and multi-frequency systems), and PPP systems.

Tallysman’s Accutenna™ technology is employed in many of our antennas.  This technology has proven its superiority for multi-path rejection which provides the receiver with the best opportunity to reliably report the accuracy of position as shown in an independent side-by-side test of the Accutenna™ technology against a single feed patch both accessing GPS L1 and GLONASS G1.
