      TW162 1-to-2 Port Smart Power GNSS Signal Splitter


      The Tallysman TW162 is a professional-grade full GNSS band signal splitter that connects one antenna to two receivers, and supports GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, BeiDou-B1/B2/B2a/B3, Galileo-E1/E5a/E5b/E6, NavIC-L5, and L-Band correction services.

      GNSS has become a critical component in safety, security, timing, and infrastructure applications, all of which require very high availability. As a result, resilient fault-tolerant components are essential to avoid service interruptions.

      The design of first-generation GNSS signal splitters suffered from a single point of failure: only one attached receiver powered the splitter and the antenna. If this receiver failed or was unplugged, all attached receivers also failed.

      Calian's current-generation TW162 Smart Power GNSS signal splitter provides two additional key features:

      First, it accepts power from all attached GNSS receivers and selects power from a receiver using the following protocol. Port #1 is given priority if its voltage is within the specified range (3.0- 12.5 VDC). However, if port #1’s receiver is disconnected or if its receiver power goes below the under-voltage or above the over-voltage specification, the TW162 will switch to the next port in numerical order, as long as its power and voltage are within the expected range. The switching and port selection is, therefore, deterministic.

      Second, if the antenna fails and does not draw current, the TW162 will provide all connectors with a current draw lower than 1 mA, indicating an antenna fault.

      The TW162 offers the best in-class performance in terms of noise figure, isolation, and linearity. In addition, it is packaged in a robust, compact, lightweight, and water-proof (IP67) corrosion-protected aluminum housing.

      The TW162 is available with either TNC or type-N connectors and offers standard gain to compensate for signal-splitting loss.

      It is recommended that unused ports should be terminated with a 50 Ohm load.
