Space communication theory and practice

Includes bibliographical references (pages 70-71)Link power budgets for estimating the quality of signal\ud transmission have been developed for space communication.\ud Essentially, a link power budget can be set up, a balance sheet of\ud gains and losses for the signal transmission path, as a tool to\ud analyze the performance of the entire communication link. Examples in\ud this paper illustrate the uses of link power budget analysis for\ud geostationary communication satellites, deep space orbiting probes,\ud satellite-to-satellite crosslinks, and ship-satellite-shore\ud communication links
