TW5394 Smart GNSS Antenna; High Precision; Precise Heading; u-blox ZED-F9P + NEO-D9S

The TW5394 is a multi-band (L1/L2), multi-constellation integrated GNSS receiver/antenna with integrated L-Band receiver for PointPerfect Flex PPP-RTK corrections. The TW5394 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 to support the most demanding navigation, automation and precision mobility applications. Two TW5394’s may be combined as a Moving Base RTK Precise Heading base and rover pair.

Interference Resilience
The TW5394 incorporates a latest generation multi-band (L1/L2) GNSS receiver with a Tallysman Accutenna® multi-band (L1/L2/LBand) 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 TW5394 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.

Precise Point Positioning
The TW5394 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.

The TW5394 may also be configured to operate in an RTK mode as either a base or rover for sub cm precision. For Precise Heading applications, two TW5394’s may be arranged as a moving base RTK base and rover pair. The base device may receive PPP-RTK corrections for increased positional accuracy while concurrently sending RTCM correction messages to the rover.
