Five candidate data, voice, and ranging modems were evaluated by the AEROSAT channel simulation facility to determine applicability for use in the aeronautical satellite communication channel for air traffic control. The modems were supplied by Telecommunications Radio-electriques et Telephoniques of Paris, France. The modems performance were evaluated as a function of carrier to noise ratio, carrier to multipath ratio, doppler frequency, and relative doppler frequency. The results are presented herein. Author
