This book was released on 2018 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern proposals for Low Earth Orbit (LEO) satellite constellations underscore the tremendous potential and versatility of distributed spacecraft missions (DSMs), but they have also begun to stress the limits of the existing development paradigm. A new generation of LEO constellations is emerging, and understanding the related technical, economic, and policy landscapes will be critical to fostering their success. The most significant value of this research effort comes from its breadth. LEO constellations are becoming essential tools for a wide range of applications, and this work seeks to examine the diverse set of topics facing modern constellation stakeholders. Through a multidisciplinary, systems engineering evaluation, this thesis synthesizes current knowledge gaps and questions related to second-generation LEO constellations. The investigation begins with a discussion of the historical development of DSMs, and three distinct eras of constellation use are identified. The initial time period, 1959 to 1996, captures the early DSMs that framed the development of modern systems. The first generation spans from 1997 to 2009. It begins with the installation of the first commercial, telecommunications constellations and demonstrates logistic growth for commercial DSM member spacecraft. Growth rates surge again as the second generation begins in 2010, and the data reflect current trends toward commercial, remote-sensing applications of DSM systems. The second generation of LEO constellations coincides with an approximately 189% increase in the annual NGSO satellite launch rate and a 92% increase in the number of constellation systems initialized each year over the first generation. This work continues by underscoring technologies that have enabled this growth through a survey of relevant literature and patent filings. Contemporary issues in constellation technology policy are also examined. Through a series of cost and risk focused case studies, limitations within the existing development and maintenance paradigms are illustrated. The new generation of constellations is challenging the assumptions that have traditionally guided such analyses, and opportunities for further framework development are discussed. This thesis represents a contribution to the advancement of constellation systems by assessing the viability of the existing paradigm and identifying critical areas of future research.

Book Synopsis Optimizing Coverage and Revisit Time in Sparse Military Satellite Constellations: A Comparison of Traditional Approaches and Genetic Algorithms by :
Download or read book Optimizing Coverage and Revisit Time in Sparse Military Satellite Constellations: A Comparison of Traditional Approaches and Genetic Algorithms written by and published by . This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sparse military satellite constellations were designed using two methods: a traditional approach and a genetic algorithm. One of the traditional constellation designs was the Discoverer II space based radar. Discoverer II was an 8 plane, 24 satellite, Low Earth Orbit (LEO), Walker constellation designed to provide high-range resolution ground moving target indication (HRR-GMTI), synthetic aperture radar (SAR) imaging and high resolution digital terrain mapping. The traditional method designed 9-ball, 12-ball, 18-ball, and 24-ball Walker constellations. The genetic algorithm created constellations by deriving a phenotype from a triploid genotype encoding of orbital elements. The performance of both design methods were compared using a computer simulation. The fitness of each constellation was calculated using maximum gap time, maximum revisit time, and percent coverage. The goal was to determine if one design method would consistently outperform the other. The genetic algorithm offered a fitness improvement over traditional constellation design methods in all cases except the 24-ball constellation where it demonstrated comparable results. The genetic algorithm improvement over the traditional constellations increased as the number of satellites per constellation decreased. A derived equation related revisit time to the number of ship tracks maintained.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
