I'll add something to that effect. A GEO orbit is one with an altitude of
around 36,000 km. A GSO orbit has the additional constraint of being over
the equator (inclination = 0 deg.).
The reason that I specified GSO instead of just GEO is that the GSO orbits
are a subset of GEO orbits where the satellite appears to be stationary in
the sky and the path length from a fixed ground station to the satellite is
constant. The more general GEO term does not necessarily imply that,
although most people use the term GEO to mean GSO because that's where the
satellites tend to be. The key point, however, is that for GSO there is a
long propagation delay, but that delay is relatively constant. That is not
the case for inclined GEO.
Thanks for your comments.
