A summary description of an L-band multipath/ranging/diital communication experimental program is given. Tests involved an FAA KC-135 jet airplane, the NASA ATS-5 satellite, the NASA/Rosman ground station, and the FAA NAFEC facility. All tests were conducted within the 1545- to 1655-MHz frequency band allocated for future aeronautical services. Tests included 30 overocean multipath and ranging flights in the North Atlantic region, 16 digital data communication tests, eight overland multipath flights including both summer and winter conditions, six overocean multipath flights in the Pacific region, and nine fixed-link scintillation tests. Summary test results are presented and discussed relative to theoretical expectation. (Author) See also AD-783 582.
