Tallysman GNSS Multi-Constellation Smart Antenna
The TW5340 is a multi-constellation GNSS Smart Antenna which provides simultaneous GPS | Galileo | GLONASS | SBAS reception. It is designed for use in professional grade applications such as precision timing, network synchronisation 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, GALILEO, and SBAS (WAAS, EGNOS, QZSS, Gagan, 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, resulting in much higher location accuracy.
The TW5340 supports ST Microelectronics Autonomous A-GPS which accelerates GPS positioning by predicting satellite ephemeris data based on previous observations. This results in extremely fast Time-To-First- Fix.
The TW5340 outputs standard NMEA 0183 messages with navigation update rates up to 10Hz. RS232, CMOS and USB interfaces are available with input voltage options of 3,3V, 5.0V and 12V.
The TW5340 can be configured to use satellite corrections from WAAS, EGNOS, QZSS, Gagan, and MSAS satellites to provide greater positioning accuracy.
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.
A non-magnetic version is available with Part Number TW5341
