ADS-B Out provides air traffic controllers with real-time position information that is, in most cases, more accurate than the information available with current radar-based systems. With more accurate information, ATC is able to position and separate aircraft with improved precision and timing. 3.1 ADS-B Out Data ADS-B Out data is transmitted on the UAT (978 MHz). • GPS position • Altitude • Position Integrity • Ground Track and/or Heading • Ground Speed • Velocity Integrity • Air/Ground State • Identifying information (Transponder Squawk Code, Call sign, ICAO Registration Number, Flight ID), integrity, and capability data.
