Propagation factors in the design of 20 and 30 GHz telecommunications satellite systems
Abstract
It is noted that whichever options technology and politics permit, a knowledge of the propagation factors is essential before communications satellite systems designs can be seriously considered. The paper is concerned with the area of interaction between systems options and the current knowledge of propagation factors. Attention is given to attenuation data provided by the ATS-6 during its European phase including the radiometer and radar measurements calibrated during the program. Topics covered include site to site attenuation variations, choice of polarization, and cross polarization. Discussion of systems options covers small terminal single site operation, large terminal single site operation, and small terminal diversity-site operation. Finally, the relevance of systems options to further propagation studies is considered.
