Access Control and Processing Studies for Ground-Satellite Mobile Communications/Surveillance Systems.

The report synthesizes a set of satellite communications systems configurations to provide services to aircraft flying oceanic routes. These configurations are combined with access control methods to form complete systems. These systems are analyzed using a simulation and their performance is presented in terms of avionics complexity and cost, queuing delays, pilot workload, and operational considerations. A preferred system is selected and recommendations are made. (Author)
