MARECS were two geostationary satellites – MARECS A (launched on December 20, 1981)
and MARECS-B2 (launched on November 10, 1984 – that formed part of Inmarsat's
global maritime communications satellite network. The program began as the
experimental Maritime Orbital Test Satellite (MAROTS) in 1973, but subsequently
evolved into an operational system resulting in a name change, a satellite
redesign, and delayed development.
