ADS-B Overview:
ADS-B Link Evaluation
• Goal is to evaluate available
technologies for data link delivery
of aeronautical information
• Three technologies:
– Mode S (1090) squitter
– Universal Access Transceiver (UAT)
– VHF Data Link Mode 4 (VDLM4)
• Data will support effort to establish a unified, world-wide
coordinated data link decision
• Will be evaluated in both Ohio Valley and Alaska
