TW5794 GNSS Smart Antenna for Precise Positioning

Tallysman TW5794 GNSS Smart Antenna for Precise Positioning

The TW5794 GNSS smart antenna from Tallysman is a multi-band (L1/L2), multi-constellation integrated GNSS receiver/antenna with integrated L-Band augmentation receiver for stand-alone PointPerfect® PPP-RTK applications.



The TW5794 GNSS smart antenna is capable of providing sub 6 cm PPP-RTK accuracy and sub 1 cm RTK accuracy to support the most demanding navigation, automation and precision mobility applications. Two TW5794s may be combined as a moving base and rover arrangement to offer a precise heading solution.

The TW5794 incorporates a latest generation multi-band (L1/L2) GNSS receiver with a Tallysman Accutenna™ multi-band dual-feed patch. The state of the art GNSS receiver supports concurrent tracking of all four major constellations (GPS, BeiDou, Galileo and GLONASS) in multiple frequency bands, offering high availability for PPP-RTK or RTK solutions with a quick convergence time. The multi-band architecture has proven to be a highly effective method for the removal of ionospheric error.

The TW5794 employs multi-stage XF™ filtering with low noise figure LNAs, combined with the dual feed Accutenna™, which greatly improves the rejection of multi-path signal interference.

The TW5794 incorporates an L-Band correction receiver, which offers sub 6 cm accuracy through real-time PPP-RTK corrections via the PointPerfect subscription service. (No RTK base station is required, typical of traditional RTK applications.) TW5794 offers quick convergence and continuous corrections for North America and Europe for remote regions without IP/Network coverage. PointPerfect IP streaming corrections are available in continental US, Canada, Europe, South Korea and Australia.

The TW5794 may also be configured to operate in an RTK mode as either a base or rover for sub cm precision. For Precise Heading applications, two TW5794s may be arranged as a moving base and rover pair. The moving base device may receive PPP-RTK corrections while concurrently sending RTCM correction messages to the rover.
