TW5340/TW5341 Multi-Constellation Smart Antenna The TW5340 is a multi-constellation GNSS Smart Antenna which provides simultaneous GPS/GLONASS/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 GNSS Smart Antenna uses the state-of-the-art ST STA8088 receiver which provides 32 high sensitivity tracking channels plus 2 fast acquisition channels which can be assigned to acquire and track GPS, GLONASS, QZSS, and SBAS (WAAS, EGNOS, MSAS) signals simultaneously. 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 accelerates GPS positioning by predicting satellite ephemeris data based on previous observations, resulting in extremely fast Time-To-First-Fix. The TW5340 can be configured to outputs up to three NMEA 0183 message lists with navigation update rates up to 10Hz. RS232, and CMOS interfaces are available with input voltage options of 3,3V, 5.0V and 12V to 36V with over voltage protection. 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. NMEA data can also be configured to output at RS422 levels, however the 1PPS output is disabled in this mode. 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.
