Stratus OUT

With or without WAAS GPS

Stratus ESG was designed with non-glass panel aircraft in mind. Our simplified solution includes a 1090 ES transponder and certified WAAS GPS in the same box. It’s truly an all-in-one box solution for 2020 compliance.

Stratus ES was built without GPS in order to provide affordable ADS-B Out to aircraft owners who have already invested in WAAS GPS. Stratus ES will make an aircraft rule-compliant when paired with any of the following navigators:
Garmin 430W, 530W, 6XX, 7XX
Avidyne IFD440, IFD540

Stratus IN-OUT

With or without ADS-B In

Both transponders are available in a kit that includes an ADS-B In receiver (Stratus 2i), which was designed to stay plugged into the transponder (tucked behind the panel), benefiting from external antenna signals and aircraft power.

If you already own a portable Stratus receiver, there’s an interface kit available to connect your receiver with the Stratus transponder.
