Principles of Communications SatellitesExplains the reasons, limitations and trade-offs inherent tocommunications satellites. The first half deals with link powerbudgets as well as communications hardware and examples of completelink budgets. Spacecraft technology and a description of theobjectives and basic operating methods of each of the majorsupporting subsystems are covered in the last half. Containsend-of-chapter exercises and solutions. An Instructor's Manual presenting detailed solutions to all theproblems in the book is available from the Wiley editorialdepartment. |
