uAvionix receives FAA TSO for world’s first certified drone GPS receiver – sUAS News


Today, uAvionix Corporation announced that it has received a Technical Standard Order (TSO) from the FAA for its “truFYX”Global Positioning System (GPS) receiver for Unmanned Aircraft Systems (UAS). The GPS-enabled Satellite Augmentation System (SBAS) / Wide Area Augmentation System (WAAS) is the first to specifically target UAS platform navigation and surveillance solutions.

With a greater emphasis on UAS certification for Beyond Visual Line of Sight (BVLOS) operations, truFYX provides a critical component to enable safe navigation and airspace integration. For more information on the importance of certified GPS receivers to your UAS BVLOS operation, see the latest uAvionix blog post titled “Why a certified GPS with integrity for UAS navigation issues.

Surprisingly small, the TSO-C145e Class Beta 1 GPS weighs only 20 grams, which includes the receiver, antenna, DO-160G power supply, and interface protection circuits. A class beta 1 GPS enables the truFYX to be the primary position source for home and terminal navigation, as well as the primary position source for ADS-B OUT solutions. Source Integrity Level (SIL) 3, System Design Assurance (SDA) 2 provides reception and processing by Air Traffic Control (ATC) and Traffic Collision Avoidance System (TCAS) when used as a source of position for ADS-B. For these reasons, the Airbus Zephyr program announced as launch customer of truFYX in January 2021.

A certified position source for UAS navigation reduces position errors by implementing a Autonomous receiver health monitoring (RAIM) / Fault Detection and Exclusion (FDE) engine and advanced SBAS message processing designed to improve accuracy and integrity. These systems combine to detect unhealthy GPS satellite transmissions and remove them from position computation, providing critical differentiation from a typical commercial GPS receiver. Design Assurance Level (DAL) C software and hardware are achieved through the use of RTCA DO-178C and DO-254 engineering processes. As with all uAvionix TSO certified avionics, truFYX is manufactured in Montana under a quality control process and facility approved by the District Office of Manufacturing Inspection (MIDO) of the FAA. .

TruFYX technology has already been TSO certified in several form factors including the highly integrated and complex system sky beacon, tail tag, and tailBeaconX platforms.
