Description

Mission Integrity
An aircraft is only as reliable as the weakest link. Many operators invest a fortune into equipment to ensure a stable system but are forced to settle for a consumer-level GPS source. truFYX EXT brings the same aviation integrity and design assurance found in our TSO Certified truFYX in an external-mounted option to support all aircraft types.
Safe for Passenger Operations
truFYX is the first TSO Certified GPS Position Source that brings a heritage of aviation-grade standards and reliability to UAS operations. Leveraging the same advanced fault detection and exclusion technology trusted by over 20,000+ manned aircraft – truFYX ensures your autopilot and ADS-B systems are only using the highest integrity data available. Â
Performance Based Navigation (PBN)
PBN is the art, science, and engineering of an aircraft’s ability to navigate using performance standards and understanding with complete confidence the amount of trust you can place on the calculated position. Don’t trust your mission to an unknown. Navigate with confidence.
Resistance
truFYX EXT provides increased resistance to GPS constellation errors through receiver autonomous integrity monitoring (RAIM) and fault detection and exclusion (FDE) which automatically monitors the health of the satellite constellation and removes any suspect satellites from the position calculation. Enhanced accuracy is achieved through optional ionospheric corrections.
Certified Aviation Grade Heritage
truFYX EXT is a non-certified external-mounted GPS, built to the same rigorous standards as the TSO-certified truFYX GPS. Developed for UAS BVLOS and Type Certification requirements, truFYX EXT is a critical component that brings position source integrity to your UAS platform in a compact and robust package.
Integrity = Trust
It’s 9 PM, do you know where your drone is? Do you know you can trust the position your GPS is reporting? An aviation-grade GPS with integrity like truFYX delivers not only accuracy but also integrity metrics that inform you just how trusted its calculation is. Integrity does not exist in an off-the-shelf commercial GPS.
Designed for



Search & Rescue
Urban Air Mobility
Agriculture
Would you bet your aircraft on a cellphone GPS?
truFYX EXT is the only GPS source for all missions and conditions. Developed to DO-178 and DO-254, tested to DO-160G environmental standards, and manufactured in an FAA inspected facility, truFYX EXT is entirely different from consumer-grade GPS.
One GPS for any Payload
As UAS operations grow and new regulations and mandates are introduced, truFYX EXT is a critical component designed to adapt and grow with the industry and satisfy current and future regulations.
