 Subj:	Fourth Inmarsat Code

Inmarsat, which provides telephone and Telex service to ships at sea
and to land-based portable ground stations in remote areas, has
altered the positions of its satellites.  Formerly, there were three
"regions" in which Inmarsat provided service: The Atlantic Ocean
Region (AOR), The Pacific Ocean Region (POR), and the Indian Ocean
Region (IOR).  Each has a country code.  The three are 871, 872 and
873, I don't remember which order.

Now, the AOR has been divided into two regions, East and West, served
by two separate satellites.  This eliminates a gap in land coverage in
the middle of North America where instant-gratification satellite
services like transportable telecom stations, are in demand.  The
country code for AOR West is 874.  Its Telex country code is 584.  No
change in the other three.  Note that you must now know which AOR
satellite a particular ship is pointed at before you can dial it.
