Appendix H – System description cont'd
System satellites
The satellites are positioned
in a geostationary orbit
above the equator at
approximately
35700 km altitude.
See figure.
In geostationary orbit,
each satellite moves at
the same rate as the
earth, and so remains
in the same relative
position to the earth.
The satellites cover ap-
proximately 1/4 of the earth
each, called Ocean Regions:
AOR-W Atlantic Ocean West Region
AOR-E Atlantic Ocean East Region
IOR
POR
The coverage area of the satellites for WorldPhone (Mini-M) is shown
on the map below.Communication is possible in areas marked with
