AIRCRAFT L-BAND BALLOON - SIMULATED SATELLITE EXPERIMENTS VOLUME I. EXPERIMENT DESCRIPTION AND VOICE AND DATA MODEM TEST RESULTS

This report details the result of an experiment performed by the Transportation Systems Center of the Department of Transportation to evaluate candidate voice and data modulation systems for use in an L-Band Air Traffic Control System. The experiment was designed to evaluate performance in the presence of oceanic multipath, using a high altitude balloon carrying an L-Band transponder as a geostationary satellite simulator. The voice modems chosen were Delta Modulation, Pulse Duration Modulation and Adaptive Narrow-Band Frequency Modulation. The data modems used employed PSK modulation with coherent demodulation. This is Volume I of a two-volume report. Volume II 'CW Multipath Test Results and Analyses, 'FAA-RD-73-173, details the portion of the data dealing exclusively with the measurement of oceanic multipath. (Author)
