The use of satellite technology for oceanic air traffic control

The authors discuss the use of satellite technology for communications, navigation, and surveillance within the context of providing air traffic services and control to aircraft operating in US oceanic airspace. Particular emphasis is placed on automatic dependent surveillance, a technique that uses satellite communications channels to relay position data generated by an aircraft's on-board navigation system. Using these same channels, reliable, timely, and direct pilot/controller communications can be provided within the oceanic environment.<>
