ADS-B Out via 1090 ES: Meets USA and Europe ADS-B Out Mandates. FAA ADS-B Mandate compliance requires that a suitable GPS position source such as the Dynon SV-GPS-2020 GPS Receiver/Antenna module be connected. Alternatively, a TSO’d GPS position source can be used, typically from a connected certified GPS IFR navigator.

Additional U.S. ADS-B OUT Compliance Information: The FAA ADS-B "final rule" only allows the higher power Class 1 transponder to be used as an ADS-B Out transmit device for ADS-B Out mandate compliance on or after 2020. Therefore, for U.S. customers, we recommend only the Class 1 SV-XPNDR-261.

Almost a plug and play! Easy to install. Support from Dynon and Aircraft Spruce was exceptional. Made it a breeze to install in an amateur built experimental RANS S12 XL. Integrates very well with the SV system. Set on Auto, one less thing to keep on the checklist. Now adding Dynon SV Radio and intercom for even more stress free flying!
