About the authors Walter L. Morgan is the President and a Senior Consultant at the Communications Center of Clarksburg, MD. Mr. Morgan has been in key positions in the design and use of terrestrial and satellite communications throughout his entire career. A graduate of Carnegie–Mellon University, he first worked at the David Sarnoff Research Center and then at GE′s Astro Space Division. At COMSAT Laboratories he became a Senior Staff Scientist. At the Communications Center he and his staff provide clients information on the developments, trends and forecasts in the telecommunications industries. He is the author of over 150 technical and economic papers, the Consulting Editor to Satellite Communications magazine, and Editor of the Telecommunique newsletter. Gary D. Gordon is an Aerospace Consultant in Washington Grove, MD. He received his PhD in physics from Harvard University in 1954. Dr. Gordon was 14 years at COMSAT Laboratories as Senior Staff Scientist in the Spacecraft Laboratory. He was a member of the initial Editorial Board of the COMSAT Technical Review. He has taught courses on Spacecraft Technology, Satellite Orbits, Satellite Reliability, Spacecraft Thermal Design, and Computer Programming. He has made a 26–hour videotape on Spacecraft Technology. Earlier, at GE′s Astro Space Division, he contributed to thermal design of the first weather satellite (TIROS) and was responsible for the thermal design of the Relay communications satellite. He was active in a GE education program at the corporate level teaching managers modern physics, semiconductor devices and computers. He has written technical papers on electric propulsion, geodetic use of satellites, spacecraft thermal design and a proposed 30 kW solar array.

Business Earth Stations for Telecommunications Walter L. Morgan and Denis Rouffet This practical guide provides telecommunications managers with the basic information and procedures needed to configure a telecommunications network to meet the communications needs of their organization. It offers invaluable insights into the planning needs of managers, manufacturers, sellers, and installers of microterminals. The authors give you a complete overview of microterminal technology for the next decade, including: their history and nature, why they are used, who uses them and how service is provided, potential applications, an overview of the U.S. microterminal market, a look at network operators, and the economics of microterminal versus terrestrial services. 1988 (0 471–63556–1) 234 pp. A Basic Atlas of Radio–Wave Propagation Shigekazu Shibuya Now, in one source, planners and designers of telecommunications operating organizations can get direct guidelines for radio system planning and design. Carefully organized to present basic concepts of radio–wave propagation and system design, this indispensable work fully details even the most difficult mathematical theories and equations with graphic presentations that beginners and non–specialists will find particularly helpful. It presents all of the essential design elements required for VHF, UHF, and SHF radio in easy–to–follow chart form. In addition, every problem in this book can be explored using a computer. 1987 (0 471–88183–X) 778 pp. Radio System Design for Telecommunications (1–100 GHz) Roger L. Freeman Here’s how to plan, engineer, and design analog and digital radiolinks in the point–to–point telecommunications service. Telecommunications expert Roger Freeman covers every aspect of radio system design used in telecommunications, including siting criteria, hardware layout, performance predictions, links and system analysis, facility planning, and frequency assignment information. The book also describes how radiolinks operate and how to select the necessary performance parameters and equipment specifications to meet the needs of various customers. 1987 (0 471–81236–6) 560 pp.
