MARECS
Geostationary maritime communications satellites, which form part of INMARSAT's world-wide maritime communications satellite network. The program began as the experimental Maritime Orbital Test Satellite (Marots) in 1973, but was subsequently changed to an operational system resulting in a name change, a satellite redesign, and delayed development. Marecs is operated by ESA for Inmarsat.
