This document contains Minimum Operational Performance Standards for airborne equipment to support Automatic Dependent Surveillance - Broadcast (ADS-B) utilizing the Universal Access Transceiver (UAT). ADS-B is a system by which aircraft and certain equipped surface vehicles can share position, velocity, in-situ weather, and other information with one another (and also with ground-based facilities/fixed locations such as air traffic services) via radio broadcast techniques. UAT is a multi-purpose aeronautical data link intended to support not only ADS-B, but also Flight Information Service - Broadcast (FIS-B), Traffic Information Service - Broadcast (TIS-B), ADS-B Rebroadcast (ADS-R), ADS-B Same Link Rebroadcast (ADS-SLR) and, potential future capabilities. While UAT has been expressly designed as a multi-purpose data link for surveillance-related applications, the focus of this document is on its support of ADS-B and basic ground uplink capabilities.
