Powerful Panel Mount and Remote Mount ADS-B Out
Transponders: Best in class.

The panel mount AXP340 and the remote mount AXP322 support 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.

Both the AXP340 and AXP322 transponder are 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.

Built as slide-in replacement for existing KT76A/KT78A transponders, the AXP340 is designed to easily upgrade existing Mode A/C equipment to Mode S, while adding additional functionality like a Direct-entry Numeric Keypad, Pressure Altitude & GPS Lat/Lon readout, Flight ID entry, one-touch VFR code entry, an easy-to-use Stop Watch Timer, Flight Timer, and Altitude Alerter.

The AXP340, when linked to a suitable GPS receiver, and the AXP322 when coupled with IFD540 or IFD440, transmit 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.


Your 1090Mhz ADS-B Solution

When coupled with the appropriate GPS receivers, both transponders provide full ADS-B surveillance capability to meet the upcoming mandates for flight above and below FL180 in the U.S. and internationally. Both transponders transmit the required ADS-B Out signals including your aircraft’s GPS-derived position via 1090MHz, along with ground track, ground speed and altitude information. Add in Avidyne’s Skytrax600A to the AXP340/AXP322 and you will be able to receive 1090 ADS-B/ADS-R traffic, along with active traffic.  Add in Avidyne’s Skytrax100B 978Mhz UAT receiver to receive ADS-B/ADS-R traffic as well as FIS-B weather for optimal situational awareness and safety.
