Tallysman's 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 two fast acquisition channels which can be assigned to acquire and track GPS, GLONASS, QZSS, and SBAS (WAAS, EGNOS, and 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, increasing the precision of TW5340’s smart antenna across all operating environments.

These antennas work with a number of free software applications to fully utilize the TW5340’s strengths. The VisualGPSVIEW open source GPS utility can be used to display the GPS and GLONASS GGA and GSV messages with Talker ID’s GP and GL.

Also, this VisualGPS application can log data which can subsequently be imported into the following data conversion application for easy display tracking data on Google maps.
