Tallysman Introduces our Innovative AccuAuto Line of Embedded Triple-Band GNSS Antennas for Autonomous Vehicles

The compact and rugged embedded AccuAuto antennas offer key features not available in other embedded autonomous vehicles antennas on the market.

Presently, the automobile industry is transitioning from offering GNSS-assisted navigation where the accuracy requirement is ± 3 to 5 metres (i.e., low-precision GNSS code positioning) to providing driver assistance (e.g., lane-keeping) and automonous vehicle navigation where the accuracy requirement is < 0.1 metres (i.e., high-precision GNSS phase positioning). Current roof-mounted GNSS antennas on most vehicles provide the accuracy required for navigation but they lack the precision required for assisted driving or autonomous vehicle operation. Tallysman’s new line of AccuAuto antennas are designed to provide strong clean code and phase signals that enable high-precision Real Time Kinematic (RTK) and Precise Point Positioning (PPP) navigation.

The Tallysman embedded AccuAuto vehicle antenna features a patented Tallysman® Accutenna technology multi-constellation and multi-frequency antenna element, an integrated ground plane, radome, and underside cover that provides mist and condensation protection. The bottom cover also supports the antenna cable and mitigates cable vibration to ensure the antenna has a long service life, while the ground plane improves antenna performance. All AccuAuto antenna electronic components are Automotive Electronics Council (AEC) certified and are designed to perform under the most challenging environmental conditions, such as extreme temperatures (-40 °C to +125 °C) and continuous shock and vibration.
