ATS-1 VHF COMMUNICATIONS EXPERIMENTATION.
Abstract
Eight flight tests were conducted utilizing the Applications Technology Satellite-1 (ATS-1) to obtain characteristic data of VHF communications links via satellite relay for use in over-ocean air traffic control subsystem design studies. Measurements of signal level, signal plus noise-to-noise ratio, multipath propagation, voice intelligibility, adjacent channel interference, and 75, 1200, and 2400 bits-per-second digital communications performance were obtained. Results of the tests are discussed in the report and reviewed in the 'Summary of Results' section. In general, overall communications reliability using the ATS-1 link was considered marginal.
