Photo: Tallysman Tallysman Wireless has added a line of AccuAuto vehicle antennas aimed at the autonomous vehicle market. The compact and rugged embedded AccuAuto antennas offer key features not available in other embedded autonomous vehicles antennas on the market, the company said. The automobile industry is transitioning from offering GNSS-assisted navigation where the accuracy requirement is ±3 to 5 meters (low-precision GNSS code positioning) to providing driver assistance (such as lane-keeping) and autonomous vehicle navigation where the accuracy requirement is 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 challenging environmental conditions, such as extreme temperatures (–40 °C to +125 °C) and continuous shock and vibration. Signal quality is improved with a deep pre-filter that minimizes out-of-band noise and maximizes in-band reception. This feature enables reliable GNSS signal reception in challenging urban environments, where inter-modulated signal interference from LTE and other cellular bands is common. The triple-band TWA928 supports GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b, BeiDou-B1/B2/B2a, and NavIC-L5 signals and frequency bands (the TWA928L includes support for L-band correction services).
