MARISAT -- A MARITIME SATELLITE COMMUNICATIONS SYSTEM

This paper describes the communications technique and facilities used in the MARISAT system to provide services to commercial users. The commercial portion of the system has been designed to meet performance requirements for high-quality voice and data communications between shore-based subscribers and sea-going vessels as well as other maritime installations. The commercial system configuration is described, including the C-band shore stations, the C- and L-band repeaters in the satellites, and the L-band ship terminals which operate automatically. Modulation, access, and signaling techniques are discussed to explain how network control, centralized at the shore stations, provides rapid and automatic circuit connections. Signal characteristics, frequency plans, link budgets, and system communication capacity are also presented.
