Various kinds of orbits have different purposes, especially for satellites. Learn to predict quantitatively the orbital properties of planets and satellites in a variety of situations, including near the Earth and geostationary orbits, and relate these to their uses.
A geostationary orbit is an orbital altitude at which the object in orbit having a period of the same duration and direction as the rotation of the Earth.
A geosynchronous orbit appears to hover over one spot on the Earth and is aligned to the Earth’s axis.
How to calculate geostationary and geosynchronous orbits.
