The TW5394 from Tallysman Wireless is a Multi-band (L1/L2) GNSS Antenna. It has integrated L-Band receiver for PointPerfect PPP-RTK corrections. This antenna has been designed to provide sub-1 m (standalone), sub-6 cm (PPP-RTK corrections), and sub-1 cm (RTK corrections) accuracy to support demanding navigation, automation, and precision mobility applications. It incorporates a multi-band u-blox ZED F9P GNSS receiver that supports concurrent tracking of all four major constellations (GPS, BeiDou, Galileo and GLONASS) in multiple frequency bands. This antenna has an architecture that is highly effective method for the removal of ionospheric error. It 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 TW5394 operates in the GPS/QZSS-L1/L2, GLONASS-G1/G2, Galileo-L1/E5b, and BeiDou-B1/B2 bands. It supports a broad range of L-band correction services for performance optimization to deliver a quick, precise, and reliable position solution which is resilient to interference and jamming. This GNSS antenna has a tracking sensitivity/navigation/reacquisition sensitivity of -160 dBm and a reacquisition time of 2 seconds. For Precise Heading applications, two TW5394’s may be arranged as a moving base RTK base and rover pair. It requires a DC supply of 5 V and consumes 0.6 W of power. This antenna is available in an IP69K-rated fixed-mount enclosure that measures 66.5 (Dia.) x 21 (H) mm with RJ45/RS-422 Ethernet interface.
