This is the geostationary orbit. Most communications satellites are in this type of orbit. A satellite in a polar orbit travels over Earth's poles, as the Earth turns underneath. Weather satellites and Earth observation satellites are usually in orbits of this type. After several days, remote sensing satellites have covered almost the whole planet.
Military satellites travel in very low orbits.
The Space Shuttle travels in an orbit about 160 to 320 km high, and it can be inclined at various angles to the equator, depending on the launch angle. The shuttle flight of Canada's first astronaut, Marc Garneau, in 1984, was inclined at 57E to the equator, which allowed him to see parts of Canada not normally seen by shuttle crews. They usually travel in a more equatorial orbit. Some Russian communications satellites were put into elliptical orbit at an angle to the equator. This allowed them to travel slowly high over northern Russia for a large part of their orbit.
