uAvionix Corporation, a leader in avionics innovation, today introduced echoESX EXP, a next-generation remotely mounted, Mode S ADS-B transponder designed specifically for General Aviation (GA) aircraft. The echoESX EXP, debuting at the Sun ‘n Fun Aerospace Expo, is immediately available for pre-order and features a compact form factor, integrated SBAS GPS receiver, and seamless integration with uAvionix’s AV-30-E and AV-20-E control head panel displays.

The echoESX EXP expands the uAvionix family of easy to install, remote-mounted ADS-B transponder solutions and builds upon the pioneering tailBeaconX product. First, we put it in a tail light; now you can put it where there is no light. The echoESX EXP combines a remotely mounted Mode S transponder and 1090 MHz Extended Squitter (ES) ADS-B Out transmitter ideal for aircraft unable to accommodate the nav-light replacement form factor and the perfect solution for a new aircraft build or replacement of a traditional transponder.

Key Features of echoESX EXP:

- Integrated SBAS GPS receiver meets ADS-B Out requirements without additional hardware (only an TSO-C190 GPS antenna is required; a certified GPS antenna is optionally available from uAvionix).

- Easy retrofit using your existing transponder antenna and TSO-C190 compliant GPS antenna

- Compatible with uAvionix control heads including AV-20-E and AV-30-E which also provide altitude encoder functionality

- Compact and lightweight, based on proven ping200X and ping200XR technology

- Compliance with rigorous avionics standards (DO-181E, DO-260B, DO-229E, DO-178C, DO-254, DO-160G)

Expanding the Connected Cockpit

echoESX EXP complements the uAvionix ecosystem, integrating seamlessly with AV-20-E, AV-30-E, AV-HSI, AV-APA, AV-Link, and the ForeFlight Sentry ADS-B IN products. This ensures enhanced interoperability, providing pilots with intuitive control, enhanced situational awareness, and reduced complexity during cockpit upgrades.

“With echoESX EXP, we are delivering on our commitment to simplify ADS-B compliance and safety,” said Jon Damush, CEO of uAvionix. “This new transponder embodies the innovative spirit of uAvionix, empowering pilots to enhance their situational awareness and safety while simplifying installations and maximizing compatibility.”

The echoESX EXP for experimental aircraft is intended for use with ground-based ADS-B systems and available now for pre-orders. Shipping will begin in early Summer 2025. The certified echoESX TSO version, compatible with the certified AV-30-C control head panel display is expected in early 2026.
