1. About Stratus ES/ESG
1.1.
Overview
Stratus ES and Stratus ESG by Appareo are panel-mounted level 2els Class 1 Extended
Squitter transponders. They are Class B1S transponders which are ADS-B Out compliant.
Stratus ES and Stratus ESG respond to legacy Mode A/C interrogations and Mode S
interrogations from both ground radar and airborne collision avoidance systems. To support the
ADS-B Out function, Stratus ESG also contains a Class Beta 1 GPS/WAAS receiver. Stratus ES
receives GPS information from approved GPS position sources.
Stratus ES/ESG may be referred to as “transponder” unless product differences require them to
be identified separately.
The most recent version of this document and other Stratus ES/ESG documentation can be
