The TW5794 from Tallysman Wireless is an L1/L2-Band GNSS Antenna with a PPP-RTK accuracy of sub 6 cm and RTK accuracy of sub 1 cm. It supports concurrent tracking of GPS, BeiDou, Galileo, and GLONASS constellations and offers high availability for PPP-RTK or RTK solutions with a quick convergence time. This antenna also has an L-Band correction receiver for stand-alone RTK for precise point positioning. It includes multi-stage XF™ filtering with low noise figure LNAs, combined with the dual feed Accutenna™, which greatly improves the rejection of multi-path signal interference.
The TW5794 features a U-blox F9 engine and supports up to 184 channels. It has a cold start acquisition time of 25 seconds, an aided start acquisition time of 2 seconds, and a reacquisition time of 2 seconds. This antenna has a tracking and navigation sensitivity of -167 dBm, reacquisition sensitivity of -160 dBm, hot start sensitivity of -157 dBm, and cold start sensitivity of -148 dBm. It requires a DC supply of 5 V and consumes 1 W of power. The antenna is available in a rugged IP67-rated housing that measures 69 (Dia.) x 22 (H) mm with USB 2.0 or RS-232, RJ45 interfaces. It is ideal for demanding navigation, automation, and precision mobility applications.
