Summary

This chapter provides the mechanism of transfer of useful information to and/or from the satellite. It focuses on the use of radio waves for satellite broadcasting, communications and navigation, but briefly considers also the use of infrared and visible light for remote sensing applications. The chapter discusses how regulation and coordination of the use of the radio spectrum is an essential feature of satellite system provision. It explores the major constraints on selection of operating frequency and focuses on the various impairments to propagation through the atmosphere of radio waves, and shows that the most significant atmospheric layers from the point of view of atmospheric propagation are the troposphere and the ionosphere. The chapter describes how reflection and diffraction of radio waves can result in multiple delayed signals from multiple ray paths, which can cause fading of the received signal.
