New composite materials and semi-fabricates, as disparate in their nature as solid multilaminates and powder compacts, have been steadily increasing in importance. Their application to a variety of industrial situations is being made easier by the considerable development of conventional manufacturing techniques which fulfil many of the requirements imposed on such materials. At the same time, however, the degree of their exploitation can be limited by, either the inadequate final product properties, or simply - as in the case of particulate matter - by the inability of these techniques to produce significant quantities of the composite. For these reasons, combined with the ever increasing demand for highly sophisticated composites, attention has been focused on the dynamic manufacturing methods. Not only do they extend the range of the available routes, but they also offer the possibility of achieving chemical and/or structural syntheses of new materials from either the elemental or complex constituents. What is more, these techniques often tend to ensure integral bonding of the elements of the structure and they thus enhance the mechanical properties of the composite.

This reader-friendly resource covers the broad spectrum of satellite principles and their associated technologies. While other books limit their coverage to specialized services or to satellite payloads such as communication satellites, Satellite Systems focuses upon the methodology of launching satellites, keeping them there, the environments under which they operate, and other facets particular to their operation. Pattan's detailed, elaborate approach does not assume that the reader is versed in esoteric mathematics. Satellite Systems is specific enough to be a valuable working-tool to scientists and engineers in related fields, yet general enough to be accessible to students and interested lay people. Pattan throughly explores the concepts and technologies of satellite systems in simple, direct terms. Satellite Systems includes precise coverage of: *various orbits and the services they provide *international launch of vehicles and launch sites *phased array antennas for satellite network applications *mobile satellite services from land vehicles, aircraft, and ships *low orbit satellites for telecommunication and position determination applications *international frequency allocations for satellite control, payload management, and status *geometric relationships between satellite and Earth stations used in interference analysis, orbit determination, and location *the hostile environments in which satellites operate and cope *and much more Satellite Systems is a self-contained, extensive introduction that offers professionals and advanced undergraduate and graduate students of satellite systems the tools they need for in-depth understanding of the complexities of the subject. It is ideal as both a reference and a training text for engineers, technicians, communication lawyers, weather professionals, telecommunications experts, students, and anyone interested insatellites and satellite technology.

Although the problem of tool design - involving both the selection of suitable geometry and material- has exercised the attention of metal forming engineers for as long as this industrial activity has existed, the approach to its solution has been generally that of the 'trial and error' variety.
