TW5790 Smart GNSS Antenna; High Precision; IMU; L-Band; u-blox ZED-F9R + NEO-D9S

The TW5790 is a multi-band (L1/L2), multi-constellation integrated GNSS receiver/antenna with Inertial Measurement Unit (IMU) (for Untethered Dead Reckoning) and integrated L-Band receiver for PointPerfect Flex PPP-RTK corrections. The TW5790 is capable of providing sub 1 meter accuracy stand alone, sub 6 cm accuracy with PPP-RTK corrections and sub 1 cm with RTK corrections. Combined with the IMU to achieve Sensor Fusion, TW5790 supports the most demanding positioning applications in the most challenging environments such as a dense urban canyon and offgrid positioning.

Interference Resilience
The TW5790 incorporates a latest generation multi-band (L1/L2) GNSS receiver and IMU with a Tallysman Accutenna® multi-band (L1/L2/L-Band) triple band 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 highly 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 signal obstruction offering exceptional performance to meet the most challenging precise positioning applications.

Precise Point Positioning
The TW5790 offers support for a broad range of corrections services (RTCM RTK, networked PPP-RTK or PointPerfect Flex PPP-RTK over L-Band) 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 resilient to ionospheric errors and improves resilience against interference and jamming. As an RTK rover, The TW5790 accepts RTCM RTK messaged from a base station, Virtual Reference Station or SPARTN SSR message type via the PointPerfect Flex subscription service. The TW5790 provides sub 6 cm positioning accuracy in conjunction with PointPerfect Flex PPP-RTK corrections and sub 1 cm accuracy with RTK. TW5790 can receive PointPerfect Flex PPP-RTK corrections over L-Band when outside of terrestrial networking coverage
