STUDY OF ANTENNA AXIS CONFIGURATIONS FOR SATELLITE TRACKING AND CONTINUED STUDY OF TRANSPORTABLE ANTENNA SYSTEMS. VOLUME I.
Abstract
The purpose of this study was to select the best state-of-the-art axis configuration for transportable communications satellite tracking antennas, and to supply design information for this selection. The guide line for the study was Signal Corps tracking antenna Specification SCA 2013. The major requirements of this specification are: track communications satellites 500 to 22,400 miles high; thirty-foot parabolic reflector; transportable in military semitrailers, and C-124 and C-133 aircraft; operating frequency of 8.0 kMc; and pointing accuracy of 0.057 degree. Axis configurations utilized by existing tracking antennas were surveyed and their parameters tabled for comparison. Fortyone tracking antennas were surveyed, and are listed. A theoretical survey of possible axis configurations was conducted to determine the optimum geometrical configurations suitable for satellite tracking. Six of the most promising state-of-the-art configurations were selected, and an analytical study of these were conducted. Those studied were the A-E (narrow and wide yoke); the X-Y; and the differential and 3-axis mounts. A comparison of the analytical study is presented in tabular form, supplemented by brief summaries for each attribute compared. (Author)
