Galaxy 8i
i stands for International
This satellite was colocated with
Galaxy 3R.
It's antennas cover a larger area than the Galaxy 3R satellite, especially over
the Caribbean and Central America.
Tested from 79 deg W. Went inclined in Dec 2002.
Battery problems were reported. 3 of the 4 XIPS thrusters were announced as
failed in sep 2000. Insurance paid $93 million. This will lead the satellite to
run out of fuel in 2002. It should be replaced by
Galaxy 3C
as soon as possible.
