Antenna sold separately.


The AXP322 transponder is a remote-mounted Class 1 Mode S Level 2 Datalink Transponder, with support for 1090MHz Extended Squitter (ES), that meets all the current requirements for Mode S elementary surveillance transponders for both IFR and VFR flight. It is designed to be controlled using an Avidyne IFD540 or IFD440 GPS/NAV/COM.

Meeting the Mandate for ADS-B

The AXP322 also supports the latest Version 2 1090 MHz Automatic Dependent Surveillance Broadcast (ADS-B) Extended Squitter, known as “ADS-B out”. Equipping with ADS-B Out will be required in most U.S. airspace by 2020. The AXP322, when coupled with the Avidyne IFD540 or IFD440 transmits position information to appropriately-equipped ground stations and other aircraft. This provides improved airborne surveillance, provides vital information for airport ground surveillance, and is a key feature of future airspace plans in the U.S. and internationally.
