Geosynchronous Earth Orbit (GEO) satellites and the fast-growing Medium Earth Orbit (MEO) and Low Earth Orbit (LEO) satellites constellations are competing in the high-volume terrestrial communications market. Typically satellite communication systems are more competitive in rural area, underserved communities, and broadcast television, but the development of High Through Put (HTP) satellite technologies are having the effect of leveling the playing field compared with cable and terrestrial wireless systems.

This course provides an overview of the current satellite technology. It explains the advantages and disadvantages of satellites in the three orbital categories (GEO, MEO and LEO), the reasons why satellites have expanded operation into higher frequencies, the practical limitations of higher frequency operation and discusses some of the cutting-edge methods deployed by the satellite industry to maximize data through-put and signal availability. In addition, the course shows how the limited resource of wireless frequency spectrum is reused to multiple the satellites output. These techniques are applicable to ground base systems as well as airborne and navel applications. Some current and near future satellite systems that optimize coverage and data rates will be discussed.
