Seamless Integration for UAVs in Civil Airspace
The ZPX-A is an ITAR-free, AIMS-certified micro transponder specifically designed to enable defense UAVs to operate seamlessly in civil airspace. Derived from the proven ping200X, the ZPX-A transponder integrates Modes 3/A, C, S, and Extended Squitter (ES) ADS-B OUT, facilitating compliant airspace interoperability with minimal size, weight, and power (SWaP) footprint.
Primary Features
Certified & Compatible
ZPX-A is an ITAR-free AIMS certified micro-transponder for defense UAVs with a need to participate in civil airspace. Adapted for defense use from our TSO-certified ping200X, ZPX-A incorporates transponder modes 3/A, C, S, and Extended Squitter (ES) ADS-B OUT.
Built for UAVs, Enabling New Missions
ZPX-A enables UAVs as small as Group 1 and Group 2 to interoperate with National Airspace Systems (NAS) infrastructure and be recognized by other aircraft with Traffic Collision Avoidance Systems (TCAS) or ADS-B IN receivers. The DoD AIMS Certified ZPX-A weighs only 50-grams and draws just 1.5 watts from the aircraft’s power supply, minimizing any impact to flight time and payloads.
End to End Integrity and Control
Pair ZPX-A with the uAvionix truFYX-EXT SBAS GPS to meet the requirements of global controlled airspace delivering safe separation information to Air Traffic Control (ATC). The externally-mounted Source Integrity Level (SIL) 3 GPS guarantees visibility to certified avionics in other aircraft as well as by ATC.
The ZPX-A can be integrated with an autopilot for dynamic control from your ground control station (GCS). ZPX-A can also be carried as a payload with the uAvionix mini-controller for easy set and forget functionality.

FAQ's
Knowledge Base
What UAV classes are compatible with ZPX-A?
ZPX-A supports UAVs as small as Group 1 and Group 2 aircraft, ensuring broad applicability for tactical and surveillance missions.
Does ZPX-A meet FAA regulations for civil airspace operations?
Yes, ZPX-A meets FAA TSO-C112e, TSO-C166b, and TSO-C88b, and complies with ADS-B Out mandates (14 CFR 91.225 and 91.227) when paired with an appropriate GPS position source.
How do I install ZPX-A on my UAV?
Installation requires minimal hardware and can be surface-mounted or installed as an LRU. Ensure proper antenna connection, adequate power supply (9-30.3 VDC), and GPS integration for complete ADS-B compliance.
Can the ZPX-A be controlled remotely?
Yes, ZPX-A integrates with autopilots or GCS via standard serial interfaces, enabling dynamic in-flight transponder control, including squawk code and emergency status.
What do I do if the transponder fails to transmit ADS-B data
Check GPS connectivity, ensure a valid 3D GPS fix is achieved, and confirm proper squawk and mode settings via your control interface.
What happens if multiple GPS sources are detected?
ZPX-A will indicate a “Maintenance Required” failure. Ensure only one compliant GPS position source is connected and configured.
How can I verify correct ZPX-A operation post-installation?
Conduct a ramp test using a ramp tester like VIAVI IFR6000 or use EFB apps (like ForeFlight) to verify ADS-B transmissions.
