The experimental portion of the Aerospace program for the determination of RFI at orbital altitudes is described. The need for this effort is shown, and potential sources of RFI are outlined. The methods planned are described in detail and actual hardware for use on the first experimental flight is discussed briefly. Hardware includes antennas, preselectors, and crystal video logarithmic receivers. It is expected that results of the first experiment will be available late in 1965.
