TW5343 Multi-Constellation Smart GNSS Timing Antenna with differential serial output
The TW5343 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 multi-band capability reduces timing errors under clear skies to +/- 25 ns.
The TW5343 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 TW5343 employs Tallysman’s AccutennaTM dual feed antenna patch technology which greatly improves rejection of multi-path signal interference, across the whole GNSS band, making the TW5343 the most precise smart antenna in its size across all operating environments.
The TW5343 has differential serial output signalling for better compatibility with infrastructure applications, via RS422 transceivers.

The Best Antenna
The TW5343 employs Tallysman’s AccutennaTM 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 TW5343 accelerates GPS positioning by predicting satellite ephemeris data based on previous observations, resulting in extremely fast Time-To-First-Fix.
The TW5343 can be configured to output up to three NMEA 0183 message lists with navigation update rates up to 10 Hz. 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 on pulse-per-second signal (1PPS) synchronized to UTC time is available as a differential output at RS422 levels. NMEA data can also be configured to 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 mod parameters.
