Book excerpt: Radiometric Tracking Techniques for Deep-Space Navigation focuses on a broad array of technologies and concepts developed over the last four decades to support radio navigation on interplanetary spacecraft. In addition to an overview of Earth-based radio navigation techniques, the book includes a simplified conceptual presentation of each radiometric measurement type, its information content, and the expected measeurement accuracy. The methods described for both aquiring and calibrating radiometric measurements also provide a robust system to support guidance and navigation for future robotic space exploration.

Download or read book Deep Space Telecommunications Systems Engineering written by Joseph H. Yuen and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: The challenge of communication in planetary exploration has been unusual. The guidance and control of spacecraft depend on reliable communication. Scientific data returned to earth are irreplaceable, or replaceable only at the cost of another mission. In deep space, communications propagation is good, relative to terrestrial communications, and there is an opportunity to press toward the mathematical limit of microwave communication. Yet the limits must be approached warily, with reliability as well as channel capacity in mind. Further, the effects of small changes in the earth's atmosphere and the interplanetary plasma have small but important effects on propagation time and hence on the measurement of distance. Advances are almost incredible. Communication capability measured in 18 bits per second at a given range rose by a factor of 10 in the 19 years from Explorer I of 1958 to Voyager of 1977. This improvement was attained through ingenious design based on the sort of penetrating analysis set forth in this book by engineers who took part in a highly detailed and amazingly successful pro gram. Careful observation and analysis have told us much about limitations on the accurate measurement of distance. It is not easy to get busy people to tell others clearly and in detail how they have solved important problems. Joseph H. Yuen and the other contribu tors to this book are to be commended for the time and care they have devoted to explicating one vital aspect of a great adventure of mankind.
Download or read book Large Antennas of the Deep Space Network written by William A. Imbriale and published by John Wiley & Sons. This book was released on 2005-02-04 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important historical look at the space program's evolvingtelecommunications systems Large Antennas of the Deep Space Network traces the development ofthe antennas of NASA's Deep Space Network (DSN) from the network'sinception in 1958 to the present. It details the evolution of thelarge parabolic dish antennas, from the initial 26-m operation atL-band (960 MHz) through the current Ka-band (32 GHz) systems.Primarily used for telecommunications, these antennas also supportradar and radio astronomy observations in the exploration of thesolar system and the universe. In addition, the author also offersthorough treatment of the analytical and measurement techniquesused in design and performance assessment. Large Antennas of the Deep Space Network represents a vitaladdition to the literature in that it includes NASA-funded researchthat significantly impacts on deep space telecommunications. Partof the prestigious JPL Deep Space Communications and NavigationSeries, it captures fundamental principles and practices developedduring decades of deep space exploration, providing informationthat will enable antenna professionals to replicate radiofrequencies and optics designs. Designed as an introduction for students in the field as well as areference for advanced practitioners, the text assumes a basicfamiliarity with engineering and mathematical concepts andtechnical terms. The Deep Space Communications and Navigation Series is authored byscientists and engineers with extensive experience in astronautics,communications, and related fields. It lays the foundation forinnovation in the areas of deep space navigation and communicationsby disseminating state-of-the-art knowledge in key technologies.

Download or read book The Advanced Communications Technology Satellite written by Richard T. Gedney and published by SciTech Publishing. This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A candid insider's look at the creation of the most advanced digital communications satellite of its time that sparked a revolution in the field of communications and helped spawn Ka Band systems such as Spaceway, Astrolink, Euroskyway, and others. Although created in the early 1980's, the ACTS program correctly forecasted demand for interactive services well ahead of the rise of the Internet and used a market-based approach for defining the needed technology. The book provides a fascinating chronicle of the breakthrough events from the perspectives of the authors, who were intimately involved in every phase of the project, dramatically illustrated with scores of color graphics and photographs highlighting the hardware and the participants. Easy to read but with ample references for further research, it provides a compelling case study of a complex space system development project covering both the technical and managerial aspects. Because this material is not normally released for commercial systems, readers will obtain valuable insights into the world of high-risk technology and the role of government in sponsoring technology development for commercial systems. For communications and aerospace engineers, scientists, and technicians; executives and project managers in high-speed communications, broadcasting, the internet, and aerospace; and venture capitalists.

Available in PDF, EPUB and Kindle. Book excerpt: JPL spacecraft antennas-from the first Explorer satellite in 1958 to current R & D Spaceborne Antennas for Planetary Exploration covers the development of Jet Propulsion Laboratory (JPL) spacecraft antennas, beginning with the first Explorer satellite in 1958 through current research and development activities aimed at future missions. Readers follow the evolution of all the new designs and technological innovations that were developed to meet the growing demands of deep space exploration. The book focuses on the radio frequency design and performance of antennas, but covers environmental and mechanical considerations as well. There is additionally a thorough treatment of all the analytical and measurement techniques used in design and performance assessment. Each chapter is written by one or more leading experts in the field of antenna technology. The presentation of the history and technology of spaceborne antennas is aided by several features: * Photographs and drawings of JPL spacecraft * Illustrations to help readers visualize concepts and designs * Tables highlighting and comparing the performance of the antennas * Bibliographies at the end of each chapter leading to a variety of primary and secondary source material This book complements Large Antennas of the Deep Space Network (Wiley 2002), which surveys the ground antennas covered in support of spacecraft. Together, these two books completely cover all JPL antenna technology, in keeping with the JPL Deep Space Communications and Navigation Series mission to capture and present the many innovations in deep space telecommunications over the past decades. This book is a fascinating and informative read for all individuals working in or interested in deep space telecommunications.
