TW5354 Multi-Constellation Smart GNSS Antenna

The TW5354 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 TW5354 GNSS Smart Antenna uses a state of the art multiconstellation GNSS receiver which provides 72 high sensitivity tracking channels which can be configured to acquire and track 3 concurrent GNSS constellations (GPS, Galileo, GLONASS and Beidou) plus SBAS (WAAS, EGNOS, MSAS and GAGAN) and QZSS augmentation signals simultaneously. Differential GPS corrections may also be supplied via RTCM formatted corrrections messages.

The TW5354 employs Tallysman’s Accutenna™ dual feed antenna patch technology which greatly improves rejection of multi-path signal interference, across the whole GNSS band. The addition of pre- and post- filtering within the RF signal chain greatly improves immunity to jamming carriers typical within urban environments.

The TW5354 can be configured to output a variety of NMEA 0183 message lists with navigation update rates up to 5Hz. An RS422 interface is provided for extended range data communication with input voltage range from 5V to 36V suitable for industrial and Automotive applications.

A configurable one pulse-per-second (1PPS) synchronized to Tallymatics’ Windows™ based Configurator enables simple configuration of parameters such as baud rates, output message rates, constellation, tracking parameters and 1PPS configuration and Standby mode parameters.
