Mission Details

MARCES 1

The MARECS (Maritime European Communications satellite) satellites were members of Inmarsat's first-generation global maritime communications 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. ESA operates MARECS for Inmarsat.
