The TW5340 is a multi-constellation GNSS Smart Antenna which provides simultaneous GPS/GLONASS/QZSS/SBAS reception. It is designed for use in professional grade applications such as precision timing, network synchronization, low current applications, and tracking/positioning applications.
The TW5340 employs Tallysman’s Accutenna® dual feed antenna patch technology which greatly improves rejection of multi-path signal interference, across the whole GNSS band, making the TW5340 the most precise smart antenna in its size across all operating environments.
The TW5340 Standby mode feature provides for very low current consumption (<100uA) and is particularly useful in battery operated applications such as trailer tracking.
A standard one pulse-per-second 1PPS synchronized to UTC time is available as a single ended output or as a differential output at RS422 levels.
Tallysman’s Windows™ based Configurator enables simple configuration of parameters such as baud rates, output message rates, constellation, tracking parameters, 1PPS configuration and Standby mode parameters. A non-magnetic version is available with Part Number TW5341.
