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.

Overview of Space Technology It has been over 50 years since the rst satellite was sent into orbit, and the impact of space technology can be felt in many aspects in our day to day life. In addition to the convenience of knowing exactly where we are on the planet via GPS satellites; or deciding what to pack for a trip based on forecasts from weather satellites; watching CNNinaremotevillageviabroadcasting satellites;therearenowsomecrucialen- ronmental uses of Space technologies in the areas of natural resources management and environmental monitoring. Remotely sensed data reveals an unparallel view of the Earth for systems that require synoptic or periodic observations such as inv- tory control, surveying, agriculture, business, mineralogy, hydrography, geology, land mass cover, land utilization and environment monitoring. The advancement of remote sensing has made remote sensed data more affordable and available to merge with a variety of data sources to create mash-ups. The amalgamation of these data sources into disciplines such as agriculture, urban planning, web applications, cartography, geodetic reference systems, and global navigation satellite systems, are an important advancement of space applications and space science. Space Technology and Millennium Development Goals (MDGs) The MDGs are a set of time-bound, measurable goals and targets that are global as well as country-speci c for combating poverty, hunger, diseases, illiteracy, envir- mental degradation and discrimination against women.

This introduction to the next generation of human telecommunications enterprise examines the development of laser satellite communications and describes its advantages over previous technologies. It looks at the development of the technology and the industry through wired and wireless media and presents the vision, promise, and challenges of free-space lasers. The book balances its focused consideration of the telecommunications industry and markets with practical thoughts on creating a business involved in the introduction of commercial laser satellite communications systems. Scholars, investors, venture capitalists, policy makers, and corporate leaders will find this to be a comprehensive and eye-opening bridge between the existing telecommunications industry and the opportunities of the next generation. The opening chapters introduce the concepts of Migration, Specialization, and Interconnectivity as solutions inherent in third generation laser-satellite communications. The high capacity of the optical spectrum invites migration of applications beyond the narrow RF spectra to the high frequencies of free-space laser beams. Migration stimulates specialization of voice and duplex at the lower, optimal RF spectra. The third generation—laser-wired space—focuses around global satellite interconnectivity between fiber optics and RF. The final chapters introduce a model business concept to pioneer the third generation. Several approaches to capitalization, organization, technology development, and business strategies provide an exciting stimulus for pragmatic approaches to commercial concepts.
