Abstract:

A comparison of the advantages and disadvantages of the various communication satellites is made. This comparison leads to an analysis of the time eras in which the various systems can be made operational, and implies th t the initial application will probably be of a passive type. Reflectivity coefficients of bothACTIVE AND PASSIVE SATELLITE SYSTEMS, AND THE MATHEMATICAL RELATIONSHIP BETWEEN THE TWO SYSTEMS ARE DEVELOPED. Based upon a typical design of an active satellite system, methods are developed for increasing the reflectivity characteristic of a passive satellite to achieve the same transmission efficiency of the typical active system. This refined passive satellite system is then compared costwise with the typical active satellite system. Finally, a series of conclusions are drawn with reference to the implementation of both passive and active satellite systems. Author
