AbstractThe MITRE Corporation has conducted a three-year study of aeronautical satellite communications that culminated in a set of flight tests over the North Atlantic during August of 1985. The flight tests required the cooperation of four organizations in addition to MITRE: The Communications Satellite Corporation (COMSAT), Rockwell International, Ball Aerospace and Avantek. A test aircraft, equipped with a specially designed satellite data link terminal and antenna configuration, was flown from Cedar Rapids, Iowa across the North Atlantic to Iceland, and north of Iceland to 75° latitude. The purpose of the flight tests was to measure the performance of a full duplex aeronautical satellite data link (ASDL) using the International Maritime Satellite Organization's (INMARSAT's) spacecraft and earth station at Southbury, Connecticut, and to demonstrate potential applications. The data link operates at 200 bits-per-second (bps), uses forward error correction (FEC) coding, and employs a terminal monitor that provides interfaces to on-board avionics, data recording equipment, and an industry-standard personal computer (PC). The PC serves as a user terminal as well as a real-time monitor of bit-error-rate (BER) performance.In addition to channel propagation and BER experiments, demonstrations of potential applications of an oceanic ASDL system were conducted. A standard commercial airline data link management unit (MU) was used to communicate data over the ASDL using standard protocols. The interface to the MU allowed access to data from two distinct navigation systems: an inertial navigation system (INS) and a Global Positioning System (GPS) receiver. Aircraft position data was transmitted from the aircraft to the earth station on an automatic basis to simulate automatic dependent surveillance (ADS) of oceanic air space.This paper is divided into three sections: 1) A discussion of background issues, such as the motivation for the reported research and development, and important operational ASDL system design topics; 2) a detailed description of the developed ASDL design; and 3) a description of the test program and a preliminary summary of the results.
