TW5390 GNSS Smart Antenna

Tallysman TW5390 GNSS Smart Antenna

The TW5390 GNSS smart antenna offers IP-Network and L-Band augmentation service capability.



The TW5390 GNSS smart antenna is a multi-band (L1/L2), multi-constellation integrated GNSS receiver/antenna with Inertial Measurement Unit (Untethered Dead Reckoning) and integrated L-Band corrections receiver for stand-alone RTK for Precise Point Positioning. The TW5390 is capable of providing sub-10 cm accuracy to support the most demanding navigation, automation and precision agriculture applications.

The TW5390 incorporates the latest generation multi-band (L1/L2) GNSS receiver with a Tallysman AccutennaTM multi-band (L1/L2) 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 RTK solutions with a quick convergence time. The multi-band (L1/L2) architecture is the most effective method for the removal of ionospheric error.

The TW5390 employs multi-stage filtering with low noise figure LNAs, combined with the dual feed AccutennaTM, which greatly improves the rejection of multi-path signal interference. The IMU Sensor Fusion further mitigates the effects of severe multi-path reflections and provides continuous position availability during periods of GNSS outages caused by signal obstruction offering exceptional performance to meet the most challenging precise positioning applications.

The TW5390 incorporates an L-Band correction receiver which offers sub-10 cm accuracy through real-time PPP-RTK corrections via the Point Perfect subscription service. (No RTK base station is required, typical of traditional RTK applications.) The L-Band receiver offers quick convergence and continuous corrections in geographic regions without IP/Network coverage. PointPerfect streaming corrections are available in the continental US and Europe.

The TW5390 may also be configured to operate with the IP/ Network corrections stream when operating in a challenging urban environment where L-Band coverage may be less optimal.
