A program definition study phase I for an experimental flight test program intended to establish the capabilities and limitations of an L-band aeronautical satellite system has been completed. Three experiments are defined aircraft position surveillance via satellite, voice and digital communications via satellite, and multipath propagation characterization. The test program was designed to use the NASA ATS-5 satellite, scheduled for launch in August 1969, and two FAA airplanes, a KC-135 and a DC-6B. Ground terminals were to be located at the NASA Mojave facility in California and at the FAA NAFEC facility near Atlantic City, N.J. Descriptions of the aircraft experimental L-band antennas and functional requirements for the airborne and ground-based terminals are given. Due to failure of the ATS-5 satellite to achieve proper stabilization in orbit, the test program and hardware described herein were extensively revised prior to implementation and flight test as described in subsequent program phases.
