Abstract :
NASA´s Glenn Research Center (GRC) is responsible for the advanced communications for air traffic management (AC/ATM) project. GRC´s large-scale CPDLC (controller pilot data link communications) emulation testbed provides the capability to study the impact of data link traffic loads on the NAS communications infrastructure. The testbed provides a means of generating and observing the performance of large scale aeronautical data link communications using different subnetworks. End-to-end ATN (aeronautical telecommunications network) message (CM (context management) and CPDLC) emulation is provided through script-driven, departure-through-arrival scenarios that can support a full range of communications test activities. The capability to use up to 160 aircraft in an experiment, coupled with the testbed´s performance measurements, provides the means to assess the number of aircraft that a subnetwork can support and meet the FAA´s performance goals.
