Geostationary and Geosynchronous Orbits

This is part of the HSC Physics Syllabus Module 5: Advanced Mechanics.

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.


Applications of geosynchronous and geostationary orbits.
