Bingen, Washington, U.S.A. May 31st, 2022 – Sagetech Avionics Inc., a U.S. aerospace technology company providing industry-leading situational awareness solutions for crewed and uncrewed aerial systems announced that on Friday, May 27th, 2022, the U.S. Federal Aviation Administration (FAA) issued the technical standard order (TSO) of the MXS, Mode S Transponder with integrated ADS-B In and Out.

Sagetech’s next-gen MXS miniature transponder provides Mode A, C, S, and 1090 MHz ADS-B In/Out and is suitable for use worldwide by crewed or uncrewed systems. In addition, each transponder comes with user-friendly command and control software with a built-in traffic display for situational awareness or can be used plug and play with PX4 and Ardupilot based Autopilots. The MXS is the ideal transponder for improving aircraft visibility and safety, especially when small size and low power consumption are critical.

The MXS is the first FAA-certified small transponder to have an integrated ADS-B In receiver and is the first small, certified ADS-B receiver in the world.

”The MXS provides uncrewed and crewed aircraft OEMs with exciting options they didn’t have before, and as usual, our engineers have broken new ground with these TSOAs,” said Tom Furey, CEO of Sagetech Avionics. “Certification means safety and trust, to know that you will reliably detect all 1090 MHz ADS-B traffic.”


Key Features Included:

  • Unprecedented micro-SWaP
  • Full diversity
  • 1090 MHz ADS-B In/Out
  • Flexible I/O – RS232, RS422, ethernet
  • One box solution including ADS-B In/Out

Since Sagetech’s MXS and the MX12B DoD-certified military IFF transponder share a common hardware platform, the MX family represents the only logical solution for an OEM positioning their aircraft in both the civil and military markets.  UAS providers can simply install the MX12B for their military customers, or swap it out with an MXS for their civil customers: no additional integration, no software changes, no aircraft changes.  “It’s a truly elegant solution,” said Furey.

Sagetech created the micro-transponder segment and will continue to build on their MX capabilities. The certified MXS is the cornerstone of Sagetech’s Detect and Avoid (DAA) architecture which will support Beyond Visual Line of Sight (BVLOS) operations by their customers. Sagetech’s DAA products will accelerate the next generation of UAV-based services for both defense and civil customers.  Together with the MXS, Sagetech’s ACAS-based DAA platform will provide the most advanced, certifiable DAA system for crewed and uncrewed aircraft with onboard, full power, low SWaP collision avoidance capability.
