Tallysman TW5340 smart antenna

Click2Contact

The TW5340 smart antenna pairs Tallysman’s Accutenna technology antenna with STMicroelectronics’ Teseo II receiver. This combination makes the product suitable for use in every environment, including urban canyons.

The multi-constellation GNSS smart antenna provides simultaneous GPS/GLONASS/SBAS reception. It is designed for use in professional-grade applications such as precision timing, network synchronisation, low-current applications and tracking/positioning applications.

The device supports ST Microelectronics Autonomous A-GPS, which accelerates GPS positioning by predicting satellite ephemeris data, based on previous observations. This results in very fast time-to-first-fix.

The antenna can be configured to output up to three NMEA 0183 message lists with navigation update rates up to 10 Hz. RS232, CMOS and USB interfaces are available with input voltage options of 3.3, 5 and 12 V. The standby mode provides for very low current consumption (<100 uA) and is particularly useful in battery-operated applications.

A standard 1PPS synchronised 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.

The product is housed in an IP67 housing and is REACH and ROHS compliant. A non-magnetic version is also available as Part Number TW5341.
