Tallysman® Introduces the TW162 and TW164 Smart Power GNSS Signal Splitters

(Ottawa, Ontario, Canada, July 6, 2020) Tallysman® Wireless Inc. is excited to announce the addition of two new Smart Power GNSS signal splitters to its line of GNSS accessories.

Improve GNSS service reliability and never worry about signal reception failures with Tallysman’s new Smart Power GNSS signal splitters.  GNSS is a critical component in safety, security, timing, and infrastructure applications, all of which require very high availability. Tallysman® provides resilient, fault-tolerant Smart Power GNSS signal splitters that are essential to minimize 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.

Tallysman’s current-generation Smart Power GNSS signal splitters, the TW162 (one antenna – two receivers) and the TW164 (one antenna – four receivers), offer system redundancy and fail-over capability. First, the splitter accepts power from all attached GNSS receivers; if one receiver fails, the next attached receiver automatically provides power to the splitter and antenna. Second, if the antenna fails and does not draw current, it will provide the receiver powering the splitter with a current draw lower than 1 mA, indicating an antenna fault.

The Tallysman® TW162 and the TW164 are professional-grade GNSS signal splitters that support the full GNSS spectrum: GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b/E6, BeiDou-B1/B2/B2a/B3 and L-band correction service frequency band.

The TW162 and TW164 offer the best in-class performance in terms of noise figure, isolation, and linearity. In addition, they are packaged in a robust, compact, lightweight, and water-proof (IP67) corrosion-protected aluminum housing. The TW162 and TW164 splitters are available with either TNC or type-N connectors. Two gain options are available: standard gain to compensate for signal-splitting loss and 10 dB gain.
