Intersatellite link tracking antenna pointing requirements
Abstract
Intersatellite links (ISLs) appear advantageous for future communications satellite systems. This paper considers satellites spaced 10 deg apart on the geostationary orbit. Based on proposed communications performance goals, it discusses applicable ISL antenna acquisition and tracking system requirements and cites limitations on the initial ISL antenna pointing accuracy and the required size of the antenna scan. Also examined are particular antenna configurations (single or two-antenna), implementation concepts, and influences on spacecraft subsystems such as structure, power, and thermal considerations.
