Download or read book Satellite Communications Payload and System written by Teresa M. Braun and published by John Wiley & Sons. This book was released on 2012-08-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book primarily about the satellite payload of satellite communications systems. It represents a unique combination of practical systems engineering and communications theory. It tells about the satellites in geostationary and low-earth orbits today, both the so-called bent-pipe payloads and the processing payloads. The on-orbit environment, mitigated by the spacecraft bus, is described. The payload units (e.g. antennas and amplifiers), as well as payload-integration elements (e.g. waveguide and switches) are discussed in regard to how they work, what they do to the signal, their technology, environment sensitivity, and specifications. At a higher level are discussions on the payload as an entity: architecture including redundancy; specifications--what they mean, how they relate to unit specifications, and how to verify; and specification-compliance analysis (“budgets”) with uncertainty. Aspects of probability theory handy for calculating and using uncertainty and variation are presented. The highest-level discussions, on the end-to-end communications system, start with a practical introduction to physical-layer communications theory. Atmospheric effects and interference on the communications link are described. A chapter gives an example of optimizing a multibeam payload via probabilistic analysis. Finally, practical tips on system simulation and emulation are provided. The carrier frequencies treated are 1 GHz and above. Familiarity with Fourier analysis will enhance understanding of some topics. References are provided throughout the book for readers who want to dig deeper. Payload systems engineers, payload proposal writers, satellite-communications systems designers and analysts, and satellite customers will find that the book cuts their learning time. Spacecraft-bus systems engineers, payload unit engineers, and spacecraft operators will gain insight into the overall system. Students in systems engineering, microwave engineering, communications theory, probability theory, and communications simulation and modelling will find examples to supplement theoretical texts.

Download or read book Employing Commercial Satellite Communications Wideband Investment Options for the Department of Defense written by and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Defense (DoD) is considering major investments in systems that exploit information to support warfighting, and communications between users around the globe will be key to transmitting and using this information. In the near term, there are not enough military systems to satisfy projected communications demand and commercial systems will have to be used. In the future, budgetary pressures will make it difficult for the services to satisfy the projected communications demand with dedicated military assets. This report seeks to answer several questions: 1) How much of the projected demand can be met with programmed and planned military assets?; 2) Can commercial technologies, systems, or services meet the remaining needs? How do commercial communication assets compare with military assets in their ability to meet criteria important to DoD? What steps might be taken to mitigate shortfalls?; 3) What is the expected cost of providing the projected communications demand?; and, 4) What investment strategies should DoD employ to minimize the expected cost? The many categories of military communications include everything from battlefield communications between mobile users to communications between fixed sites in rear areas. Some of these communications must be survivable in a nuclear war, and others need high levels of protection from detection, interception, or jamming. Some require verv high data rates, whereas others need only low data rates. Some communications can be by wire or fiber optic cable, whereas others must use wireless means. We have examined a specific category of communications-high bandwidth, minimally protected satellite communications. This category of military demand represents roughly half of the projected military satellite capacity needs. To the extent that use of commercial systems can satisfy this need, military systems can be used for more specialized communications needing a greater level of control over their operation.

Download or read book Telecommunications Law and Regulation in Nigeria written by Uchenna Jerome Orji and published by Cambridge Scholars Publishing. This book was released on 2018-12-19 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nigerian telecommunications industry has continued to grow in a phenomenal manner following market liberalization reforms that commenced in the 1990s. As of 2017, the telecommunications industry was one of the fastest-growing economic sectors in Nigeria and the fourth largest contributor to the country’s Gross Domestic Product. The telecommunications industry, however, remains a highly technical and naturally dynamic industry that has not been a usual area for legal research in developing countries such as Nigeria. This book bridges that gap in knowledge by providing an analysis of the legal and policy instruments that regulate the industry. It comprises eleven chapters that discuss the historical evolution of telecommunications and its regulation; the development of the Nigerian telecommunications industry from 1886 to 2017; the legal basis for the regulation of the industry; the licensing and duties of service providers; the regulation of network infrastructure; the protection of consumers; the regulation of competition, interconnection, universal access, and environmental protection; and the resolution of industry disputes. This book will be useful to policy makers, legislators, regulators, lawyers, law students, investors, operators, and consumers, as well as any person interested in the Nigerian telecommunications industry.
