TW5790

Overview 

The TW5790 is a multi-band (L1/L2), multi-constellation integrated GNSS receiver/antenna with Inertial Measurment Unit (Untethered Dead Reckoning) and integrated L-Band corrections receiver for stand alone RTK for Precise Point Positioning. The TW5790 is capable of providing sub 6 cm accuracy to support the most demanding navigation, automation and precision agriculture applications. 

Interference Resilience 

The TW5790 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 TW5790 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 TW5790 incorporates an L-Band correction receiver which offers sub 6 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 for North America and Europe for geographic regions without IP/Network coverage. Point Perfect streaming corrections are available in continental US, Canada, Europe, South Korea and Australia. 

The TW5790 may also be configured to operate in an RTK mode as a rover offering sub-cm precision.
