TW5390C

Overview

The TW5390C is a multi-band (L1/L2/L6), multi-constellation GNSS receiver/antenna with Inertial Measurment Unit (Dead Reckoning) with integrated QZSS Centimeter Level Augmentation Service (CLAS) L6 receiver for Subscription-Free stand alone RTK Precise Point Positioning. The TW5390C is capable of providing cm level accuracy to support the most demanding navigation, automation and precision agriculture applications.

Interference Resilience

The TW5390C incorporates a latest generation multi-band (L1/L2) GNSS receiver with a Calian Accutenna™ (L1/L2/L6) 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 architecture is the most effective method for the removal of ionospheric error.

The TW5390C 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.

Corrections Applications

The TW5390C incorporates an L-Band correction receiver which offers cm-level accuracy through real-time PPP-RTK corrections via the over-the-air QZSS CLAS service (unlike traditional RTK, no base station is required). The integrated CLAS receiver offers quick convergence and continuous corrections for Japan geographic regions with and without IP/Network coverage.

The TW5390C may also be configured to output QZSS MADAOCA messages as a stand-alone QZSS L6E message receiver.

The TW5390C may also be configured to operate in a traditional RTK mode as rover offering sub-cm precision.
