ATS-5Multipath/Ranging/Digital Data L-Band Experimental Program. Phase I. Experimental Program -Aircraft Communications/Surveillance Via Satellite at L-Band.

摘要

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-5satellite,scheduled for launch in August 1969,and two FAA airplanes, a KC-135and 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-5satellite 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.
