Note: The information in the following paragraphs applies to the land mobile and maritime systems of-
fered by Inmarsat. The aeronautical services differ in channel naming, usage and system setup.
Systems
Over time new generations of satellites were launched into orbit, while new services were added. Current-
ly the third and fourth generation of satellites is in operation (3F, 4F). Inmarsat will also be the operator
of Alphasat planned for launch in 2012 which will provide L band services in Europe, Middle East and Africa
utilizing the expanded L band frequency ranges made available at WARC-03 (World Administrative Radio
Conference). The fifth generation is expected to start deployment in 2013 and will operate Ka band tran-
sponders for the new INMRASAT GlobalXpress VSAT service offering user bandwidths up to 50 Mbps.
Inmarsat started operations in 1982 with leased satellite capacity for the INMARSAT A system. The table
below shows the evolution of the various Inmarsat systems.
