TW5386 Smart GNSS UDR Antenna for High Accuracy Positioning


More Products

The TW5386 is a multi-band (L1/L2), multi-constellation integrated GNSS receiver/antenna with Inertial Measurement Unit (Untethered Dead Reckoning) and RTK for Precise Point Positioning. The TW5386 is capable of providing sub 1 meter accuracy stand alone and sub 10 cm accuracy with RTK corrections to support the most demanding positioning applications in the most challenging environments such as a dense urban canyon. 

The TW5386 offers support for a broad range of corrections services (RTK base/rover or network) allowing performance optimization according to each application’s unique requirements. The concurrent multi-band (L1/L2) access to all four satellite constellations improves the receiver’s convergence capability to deliver a quick, precise and reliable position solution which is unaffected by ionospheric errors, and improved resilience to jamming.

Interference Resilience

 The TW5386 incorporates a latest generation multi-band (L1/L2) GNSS IMU receiver with a Tallysman Accutenna™ 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. The multi-band (L1/L2) architecture is the most effective method for the removal of ionospheric error. The TW5386 employs multi-stage filtering with low noise figure LNAs, combined with the dual feed Accutenna™, which greatly improves the rejection of multi-path signal interference. The IMU Sensor Fusion further mitigates 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. 

Weather any storm

Housed in an industrial-grade weatherproof IP69k enclosure, the TW5284 will stay safe and secure wherever your fleet goes.

Don’t let your cabling fail you

Noisy environments and long cable runs need a more industrial approach, therefore we have added industrial grade RS422 transceivers to our Tx, Rx and 1PPS signals.

Mitigate interference

Tallysman’s Accutenna™ technology offers unmatched precision that outperforms any single-feed patch antenna, so you can stay connected to your fleet even in the most crowded areas.
