Stratus is a portable, battery-operated receiver that works in conjunction with the ForeFlight Mobile app. It provides pilots with free in-flight weather and traffic and is a source of accurate GPS WAAS position. Stratus receives Automatic Dependent Surveillance - Broadcast (ADS-B) weather information (FIS-B), traffic information (TIS-B), and other related data and broadcasts it to ForeFlight Mobile via a WiFi network.
