This chapter begins with the procedures and techniques used to analyze the mobile communications channel, with focus on the satellite mobile channel. The result is to modify the basic link power budget equation to account for mobile channel effects, and provide a basis for the design and performance evaluation of mobile satellite systems. Local conditions for the satellite mobile channel, can be categorized into three general propagation states: multipath, shadowing or blockage. The chapter focuses on single satellite links operating with the mobile terminal. Single satellite mobile systems tend to be at the geosynchronous earth orbit (GSO), with a fixed elevation angle and azimuth. Multi‐satellite mobile constellations, primarily operating in non‐GSO (NGSO), are also in use, and provide an additional advantage of satellite diversity to improve link availability and performance to the mobile terminal. The chapter considers uncorrelated fading and correlated fading separately.
