Since the launching of the MARISAT satellites in 1976, the system has provided reliable teleprinter and voice grade service, including facsimile and 1200/2400-bit/s data. It presently serves ships in three oceans, and experience indicates rapid growth in both utilization and the number of ships equipped for service. Long before the MARISAT system became fully operational, it was recognized that the satellites could provide inexpensive, ship-to-shore, high-speed, data transmission service. The operational concept for such service at 56 kbit/s was disclosed in 1977. During the latter part of November 1978, simplex 56-kbit/s data transmission tests (over 130 hours in about two weeks) were conducted from a ship in the North Sea to the MARISAT shore station in Southbury, Connecticut. The test results effectively demonstrated that a 56-kbit/s ship-to-shore data transmission service could be implemented for small ships with a high degree of reliability and availability, and, with minimal additional equipment, to a standard MARISAT ship terminal.
