Want this question answered?
Geosynchronous satellites ('stationary' ones that is) are usually 36 000 km above the Equator, and thus appear to be fixed relative to a given location on earth. They are comm satellites, but because of the distance, the return trip for a signal to them is about 1/4 second. This delay causes trouble with phone comms. You must have been annoyed by those attempts at 'live' TV interviews via such a system. However, for latitudes above say 55o, the sight path to the satellite becomes closer to to horizontal at that site, and may be blocked by buildings, mountains, etc. To service these latitudes, geostationary satellites are positioned to have their rotation plane inclined to the equator. This improves their performance for comms, but at the expense of them no longer appearing to be stationary in the sky.
There are not. In fact, there are no satellites which remain in either the northern or southern hemispheres. Every satellite spends equal time passing over each of them. The only minor exception would be communications satellites in equatorial geosynchronous orbits, where the satellite is essentially "parked" over one spot above the equator.

GPS satellites orbit at 11,000 nautical miles above the Earth
There are several thousand. About 30 of them are GPS satellites, and another several dozen are geosynchronous communications satellites that provide TV programming and telephone service. There is the Hubble Space Telescope, the International Space Station, and hundreds of weather satellites.
There are currently 32 GPS satellites Orbiting earth at 20,000Kms above sea level There are also 24 GLONASS satellites (The russian version of a GPS satellite) Which many high end GPS receivers will use in conjunction with the standard GPS satellites. These orbit a little lower than GPS at arond 19,000Kms above sea level. There are 4 Galileo Satellites, which are currently un used, but are the start of the European satellite constealltion which is a work in progress. They orbit at 24,000Kms above sea level. On top of all that, there are 10 Chinese navigation satellites called COMPASS orbiting in an orbit above China and Asia. They orbit at around 21,000 Kms above sea level.
All satellites follow an elliptical orbit - they are darn close to circular, but even a circle is an ellipse.
They point to geosynchronous satellites in orbit above the equator. South for the northern hemisphere and north for the southern.
A geosynchronous orbits refers to the orbit of a satellite that matches the rotation of the earth, allowing it to remain above the same line of longitude. The satellite may still move north and south but not east or west. A geostationary orbit is a specific type of geosynchronous orbit directly above the equator. This allows the satellite to remain completely stationary over a fixed point on the earth's surface.
satellites are located 37,000 km above the earth's equator.

Some are (geosynchronous are not).
Yes, the satellites orbit in a geosynchronous orbit, as with most all communications satellites. (Some exceptions are satellites such as the global positioning satellites.)

In geosynchronous orbit, it's always somewhere over the same meridian of longitude.In geostationary orbit, it's always over the same point on the equator.
