Transponder Redefined

Mode S ADS-B OUT Transponder

Mode S + ADS-B OUT Transponder meets airspace requirements worldwide.

Integrated Certified GPS Receiver

tailBeaconX includes a certified SBAS GPS receiver and antenna. No additional GPS is required.

ADS-B from Space

The tailBeaconX with integrated dipole antenna is specifically designed to maximize performance when
tracked by space-based ADS-B satellite constellations.

LED Lighting

The integrated 20,000 hour rated LED position light ensures the tailBeaconX draws less power than your
old incandescent bulb.

Think Outside the Airframe

tailBeaconX is the world’s first transponder designed as a rear position light replacement. The 1090MHz Mode S ADS-B OUT transponder satisfies the requirements for all existing and inevitable ADS-B regulations worldwide, especially those leveraging space-based ADS-B. Fly knowing no matter your destination, tailBeaconX will keep your aircraft connected.

“Believe it or not‭, ‬that’s exactly what the tailBeaconX is‮—‬a Mode S transponder‭, ‬WAAS GPS for position information and an LED taillight all in one crazy‭-‬compact‭ ‬unit‭”

World-Wide Coverage

tailBeaconX embraces the future, providing precise ADS-B data to satellite networks without the need for diversity antennas. When it comes to terra firma, tailBeaconX also exceeds the performance of traditional panel installed transponders that use belly mount antennas.

Less Ground Time
Easiest Install

tailBeaconX mounts in place of your existing rear position light.  The GPS, space-based, and ground-based antennas are integrated in to the lens housing.  No new holes or pentetration of pressure vessels are required making tailBeaconX the lowest-hassle easiest install period.

  • Aircraft Down Time



Diversity Transponders

Install Comparison

  • tailBeaconX
  • Other Diversity Transponders

tailBeaconX only requires serial control to the rear position light location. No new antennas to mount, no new holes in the airframe. The cost and complexity of the tailBeaconX installation is minimal.

A traditional diversity installation requires three seperate antennas. The GPS antenna and transponder antennas are typically not included increasing cost. Each antenna requires a separate coaxial run. In most cases, the entire aircraft interior must be removed to complete the installation. Labor for the installation typically exceeds the cost of the equipment.

Looking to the Future

tailBeaconX is the first commercially available avionics solution developed with the needs of Urban Air Mobility (UAM) in mind. Electric Vertical Take Off and Landing (eVTOL) aircraft, powered by batteries and alternative fuels, require radically different solutions than those that exist today. tailBeaconX weighs only 90 grams, takes no critical volume from an internal avionics bay, incorporates its own antennas, and draws only 3 watts of power. This results in longer flight times and higher payload capacity for the next generation of airborne mobility.

Instant Setup and Configuration

Mechanically installing tailBeaconX is the first easy step. With uAvionix’s mobile app, configuration is just as simple. Our mobile application (available for both Apple iOS and Android) guides your installer through setting the necessary values including the ICAO address, emitter type, aircraft length, width and GPS offsets.

More than a Mandate

The AV-20-E and AV-30 have been upgraded to include transponder control functionality! The tailBeaconX combined with the AV-30-E or AV-20-E multiplies your cockpit functionality while future-proofing your ADS-B system to meet current and inevitable mandates worldwide.
