This report describe the results of a series of laboratory, field, and flight test experiments designed to characterize the performance of current VHF communication equipment and the VHF channel relative to the communication of digital data in the ATC environment. The experiments were conducted at data rates of 2400 and 4800 bits per second with minimum-shift-keying MSK as the baseband modulation. Laboratory experiments were performed to determine the performance of individual VHF communications equipments and subsystems of equipments in Gaussian noise and simulated multipath environments. Field tests utilizing continuous psuedo-random data streams were conducted at Logan Airport, Boston, to obtain estimates of VHF data link performance in the multipath environment of an airport surface. Flight tests were performed utilizing continuous psuedo-random data streams transmitted air to ground to determine bit and block error rates, received signal level, signal fading characteristics, and geographical coverage.
