i think you meant for the types of orbits synchronus and geostationary... anything that's orbiting the earth can be seen as sychronus.
anyway, i really don't know much about how satellites are apportioned out, but you seem like you want to know more about satellites, so here's some
there are three basic types of orbits: low earth orbit, medium earth orbit, and geostationary orbit. there is also one orbit, sun sychronus.
low earth orbit is generally used by survailance and photographic satellites. the orbits are also 1200 miles or less up.
medium earth orbit is about 6000 miles up, and is mostly used for navigational and communications satellites.
geostationary orbit is used for TV and communications. the orbits take exactly one day to revolve around the earth, and are placed directly above the
equator. because of this the satellites seem to stand still as seen from earth.
a sun sychronus orbit is an orbit when the satellite passes over the same spot on earth at the same time every day.
