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 highsensitivity 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 mostprecise 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 tooutput at RS422 levels, however the 1PPS output is disabledin 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 modeparameters.
