Tallysman TW5386 Smart GNSS UDR Antenna for High Accuracy Positioning

Tallysman TW5386 GNSS Smart Antenna with UDR

The TW5386 GNSS smart antenna is a multi-band, multi-constellation integrated GNSS receiver/antenna with Inertial Measurement Unit (Untethered Dead Reckoning) and RTK for Precise Point Positioning.



The TW5386 GNSS smart antenna 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 incorporates a latest generation multi-band (L1/L2) GNSS IMU 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. 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 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 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.

The TW5386 accepts RTCM RTK messaged from a base station, Virtual Reference Station or SPARTN SSR message type via the Point Perfect subscription service.

The TW5386 provides sub 10 cm positioning accuracy in conjunction with RTK applied corrections.
