truFYX

SBAS Global Positioning System (GPS)

Overview

truFYX is the world’s first Technical Standard Order (TSO) certified SBAS Global Positioning System (GPS) position source designed specifically for Unmanned Aircraft Systems (UAS) autopilots and Automatic Dependent Surveillance – Broadcast (ADS-B) OUT solutions. The truFYX incorporates the GPS receiver and antenna into a single 24mm radius / 20g waterproof enclosure.

Reduce your onboard GPS count by leveraging truFYX as the primary position source to your autopilot and ADS-B solution.

FAA TSO Certification Pending

FAA TSO-C145e, Class Beta 1 GPS provides for:

  • Primary position source for domestic en route, terminal, approach (LNAV), and departure navigation

  • Integrity in the absence of the SBAS signal through the use of Fault Detection and Exclusion (FDE)

  • Enhanced accuracy with processing of optional ionospheric corrections

  • Meeting worldwide compliance requirements for controlled airspace access pre- and post- 2020 ADS-B mandates in the U.S. and E.U.
