Inmarsat 2-F1



Inmarsat 2-F1 was a maritime satellite launched using the Delta launch vehicle from Cape Canaveral Air Force Base for the International Maritime Satellite Organization. It was a new-generation mobile communications satellite and was box-shaped, 2.5 m high by 1.5 m long by 1.4 m wide. Solar arrays spanning 15.2 m provided 1,200 W. The communications payload, supplied by Hughes Aircraft Company, provided 250 ship-to-shore, shore-to-ship, aeronautical and land mobile voice circuits. The mobile link was via L-band; fixed-ground links via C-band. The payload used 4 separate cup-dipole phased-array antennas for both frequencies. Stationed above 64.5 deg e, it increased transmission capacity over the Indian Ocean area by a factor of six.
