TW5387 Smart GNSS Antenna; High Precision; IMU; ST TESEO V (Quectel LG69TAP)

The TW5387 is a multi-band (L1/L5), multi-constellation integrated GNSS receiver/antenna with Inertial Measurement Unit (IMU) (for Untethered Dead Reckoning) and RTK for Precise Point Positioning. The TW5387 is capable of providing sub 1 meter accuracy stand alone, and 1 cm accuracy with with RTK corrections. Combined with the IMU to achieve Sensor Fusion, TW5387 supports the most demanding positioning applications in the most challenging environments such as a dense urban canyon.

Interference Resilience
The TW5387 incorporates a latest generation multi-band (L1/L5) GNSS receiver and IMU with a Tallysman Accutenna® multi-band (L1/L5) dual feed patch. The state of the art GNSS receiver supports concurrent tracking of three major constellations (GPS, BeiDou, and Galileo) in multiple frequency bands. The multi-band (L1/L5) architecture is highly effective method for the removal of ionospheric error. The TW5387 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 with GNSS data and optionally speed data 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.

Real Time Kinematic Positioning
The TW5387 offers support Real-Time Kinematic base/rover corrections allowing performance optimization to sub 1 cm. The concurrent multi-band (L1/L5) access to three 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 TW5387 accepts RTK RTCM messages from a base station to act as a rover in RTK mode, and includes IMU. The TW5387 provides sub 1 cm positioning accuracy in conjunction with applied RTK corrections.
