TW5350/TW5351

The TW5350 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 TW5350 GNSS Smart Antenna uses the state-of-theart multi-constellation 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 TW5350 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 TW5350 can be configured to output a variety of NMEA 0183 message lists with navigation update rates up to 5Hz. An RS232 interface is provided for data communication with input voltage options of 3.3V and 5-36V with over-voltage protection.

A configurable one pulse-per-second (1PPS) synchronized to UTC time is made available as a RS422 differential signal. 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.

A non-magnetic version is available with Part Number TW5351.
