Considerations relating to geostationary intersatellite links
Abstract
Factors affecting the frequency reuse potential of geostationary intersatellite links and their impact on orbit spectrum utilization efficiency are discussed. The use of such links may be to interconnect widely separated earth stations, to alleviate satellite orbit location constraints, and to permit international programs exchange. The links offer high reuse potential and may accommodate several hundred intersatellite links within acceptable interference bonds. It is found that reuse potential is improved by a high sidepole discrimination and low orbit ellipticals, resulting in the highest orbit spectrum utilization efficiency. In addition, interleaving is not possible in short links with codirectional frequency assignments, but higher antenna discrimination and lower orbit ellipticity allow the smallest possible link length. It seems that a maximum antenna beamwidth for links and maximum orbit eccentricity for space stations are worth developing.
