Marisat satellites were the first maritime telecommunications satellites and were designed to provide dependable telecommunications for commercial shipping and the U.S. Navy from stable geosynchronous orbital locations over the three major ocean regions. The three Marisat satellites, F1, F2, and F3, were built by Hughes Aircraft Corporation (HAC) for COMSAT Corporation starting in 1973. The satellites were designed to provide maritime telecommunications services in three large ocean areas, the Atlantic Ocean, the Pacific Ocean, and the Indian Ocean, and were located at 72.5° East longitude, 176.5° E, and 345° E in the geosynchronous orbital arc. The three-satellite Marisat system served as the initial INMARSAT constellation.

  • Marisat est une famille de trois satellites de télécommunications américains circulant en orbite géostationnaire développés pour répondre aux besoins de la marine de guerre américaine et de la marine marchande. Ce sont les premiers satellites entièrement dédiés aux communications maritimes. Les trois satellites sont lancés en 1976. En 1982 à la suite de la création de l'organisation internationale Inmarsat dédiée aux communications spatiales maritimes, la gestion des trois satellites, désormais entièrement dédiés aux communications à usage civil, est prise en charge par cette nouvelle organisation.

  • 매리샛(Marisat) 위성들은 최초의 해군용 통신위성이며 세 곳의 주요 대양 위의 안정적인 지구 동기 궤도 지점으로부터 상업적인 선적과 미국 해군을 위한 의존적 전기통신을 제공하기 위해 설계되었다. 매리셋 위성 F1, F2, F3은 휴즈 항공(HAC)이 1973년을 기점으로 을 위해 제조한 것이다. 이 위성들은 대서양, 태평양, 인도양에서 해양 전기통신 서비스를 제공하기 위해 설계되었으며 72.5° E 경도, 176.5° E, 345° E 지구 동기 궤도에 위치하였다. 이 3개의 매리샛 위성의 소유주는 COMSAT 코퍼레이션이 2000년 록히드 마틴에 인수되면서 록히트 마틴으로 변경되었다. 이 세 위성은 모두 1976년에 발사되었다.

The three-satellite Marisat system served as the initial INMARSAT constellation. Ownership of the three Marisat satellites was transferred to Lockheed Martin when it bought COMSAT Corp in 2000. The Marisat-F2 satellite was acquired by INTELSAT as part of the COMSAT General Corp. acquisition in October 2004. The three satellites were all launched in 1976. MARISAT F1 was launched on 19 February 1976, MARISAT F2 was launched on 10 June 1976, and Marisat F3 was launched at 22:44 GMT, 14 October 1976. Launch vehicle for the satellites was the McDonnell Douglas 2914 Delta rocket. The satellites were launched from Cape Canaveral by the National Aeronautics and Space Administration under contract with COMSAT. In 1981 the INMARSAT took over from the Marisat system. (en)
