THE WORLD'S FIRST MARITIME COMMUNICATIONS SATELLITE SYSTEM

COMSAT General, An independent subsidiary of the Communications Satellite Corporation (COMSAT) and the major participant in the establishment of MARISAT, the world's first satellite communications system for use by international shipping recently announced that its first satellite is scheduled for launch in early 1975. A second summer launch will follow, thus creating an initial two-ocean system. Utilizing existing land line facilities, an owner will communicate through antennas at two locations via satellite with his ships at sea. Ships utilizing the MARISAT System will have a weather-protected steerable antenna above deck with a solid-state transmitter and receiver. Below deck there will be a communications console with an antenna control unit and communications equipment to provide ship-to-shore communications 24 hours per day. Initial service offerings will include: VOICE--A capability from any ship in the Atlantic or Pacific to interconnect with the domestic telephone network. HIGH SPEED DATA--A capability for alternate voice data communications at 1,200 and 2,400 bits per second. TELEX--A capability to transmit and receive telex messages and to interconnect with the world-wide teletype network. FACSIMILE--A capability to transmit drawings, manifests, weather maps, and other graphics that can now be transmitted domestically via the telephone network.
