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 RTK corrections. Incorporating an 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 the latest generation multi-band (L1/L5) GNSS receiver and IMU with a Calian 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 the 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 RTCM Real-Time Kinematic 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. 

The TW5387 works with Point One Navigation’s Polaris N-RTK service and Swift Navigation Skylark N-RTK service.
