The TW5990 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 u-blox PointPerfect® PPP-RTK augmentation service. The TW5990 is capable of providing sub 10 cm accuracy to support the most demanding navigation, automation and precision agriculture applications. The TW5990 is specifically packaged for OEM automotive applications in an Automotive grade fixed Mount package with built-in ground plane.

Interference Resilience

The TW5990 incorporates a latest generation multi-band (L1/ L2) GNSS receiver with a Calian 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, 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 TW5990 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 TW5990 incorporates an L-Band correction receiver, which offers sub 10 cm accuracy through real-time PPP-RTK corrections via the PointPerfect 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 continental US and Europe.

The TW5990 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.
