8、is a wideband broadcast data link operating on 978 MHz with a channel modulation rate of just over 1 Mbps. By design, UAT supports multiple broadcast services, including flightJnformation services (FIS-B) and traffic information services (TIS-B), in addition to automatic dependent surveillance broad

9、cast (ADS-B). This is accomplished using a hybrid medium access approach that incorporates both time-slotted and random unslotted access. By virtue of its waveform, modulation rate, precise time reference and message-starting discipline, UAT can also support independent measurement of range to most

10、other participants in the medium. There are two basic types of broadcast transmissions or messages on the UAT channel: the UAT ADS-B message and the UAT ground uplink message. The UAT ADS-B message is broadcast by an aircraft to convey its state vector 215 11 “MESSAGE DATA BLOCK TYPE CODE“ field enc
