Hydrometeor Attenuation on Satellite Paths,ncies above 10 GHz. Precipitation can have many forms in the atmosphere. Hydro-meteor is the general term referring to the products of condensed water vapor in the atmosphere, observed as rain, clouds, fog, hail, ice, or snow. The presence of hydrometeors in the radiowave path, particularly rain, ca

Rain Attenuation Prediction Methods,l location at the specific frequency of interest. Direct long-term measurements of rain attenuation for all of the ground terminal locations in an operational network are not practical, therefore modeling and prediction methods must be used to make a best estimate of the expected attenuation for eac

Introduction,applications. These satellite systems rely on the transmission of radiowaves to and from the satellite and are dependent on the propagation characteristics of the transmission path, primarily the earth’s atmosphere. Radiowave propagation thus plays an important part in the design and ultimate performance of space communications systems.

Fundamentals of Radiowave Propagation,enna gain, and polarization, are defined. Radiowave propagation modes and propagation mechanisms are discussed and the importance of the ionosphere and the troposphere in space communications is highlighted. Finally, the major radio-wave propagation factors in the frequency bands of interest to space communications are introduced and described.
