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.

The book explores the low-noise microwave systems that form the front end of all DSN ground receiving stations. It explains why the front end of each antenna is key to establishing the sensivity, polarization, frequency diversity, and capabilities of the receiving chain and, therefore, the entire ground station.

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.

the wave theory foundations of today's radio occultation techniques Forty years ago, the premier radio occultation problem was how to profile the atmosphere and radius of Mars using signals sent by the Mariner 4 spacecraft. Researchers then could rely on ray theory-based techniques for accurate analysis of the thin, uniform Martian atmosphere. Today's radio occultation challenges mostly involve communications platforms—and related data, instrument systems, and applications—in the Earth's own atmosphere. To deal with the density and complexity of this multilayered medium, an analytical framework that goes beyond ray theory is needed. Setting the cutting edge for the field, Radio Occultations Using Earth Satellites: A Wave Theory Treatment develops a purely wave-theoretic approach to occultation analysis. This approach yields more nuanced results than either ray or hybrid (ray/wave) methodologies offer, and proves suitable for the many variables at work in today's problems. This groundbreaking text provides: An introduction to the general theory of radio occultations Development of ray theory and scalar diffraction treatments of radio propagation processes Development of a wave theoretic treatment of the above wave propagation processes The correspondence between wave and ray theories A discussion of how to use a wave-theoretic approach to infer the refractive properties of the propagation medium from a time series set of observations of the propagated wave's phase and amplitude A comprehensive resource that clearly defines the latest topics and methodologies, Radio Occultations Using Earth Satellites is a must-have text for engineers, scientists, students, and managers in satellites communications, navigation, deep space and planetary exploration, aerospace, atmospheric science, physics, and engineering. The Deep Space Communications and Navigation Series is authored by scientists and engineers with extensive experience in astronautics, communications, and related fields. It lays the foundation for innovation in the areas of deep space navigation and communications by disseminating state-of-the-art knowledge in key technologies.

"Pioneer 10 is the first spacecraft to fly beyond the orbit of Mars and through the Asteroid belt, it made the first series of "in situ" measurements of Jupiter's environment, it provided the first close-up pictures of the giant planet and finally, Pioneer 10 is the first man-made object to leave the solar system. Pioneer 11 is the first spacecraft to fly to the ringed planet Saturn."--Foreword.

A valuable reference for students and professionals in the field ofdeep space navigation Drawing on fundamental principles and practices developed duringdecades of deep space exploration at the California Institute ofTechnology's Jet Propulsion Laboratory (JPL), this book documentsthe formation of program Regres of JPL's Orbit DeterminationProgram (ODP). Program Regres calculates the computed values ofobserved quantities (e.g., Doppler and range observables) obtainedat the tracking stations of the Deep Space Network, and alsocalculates media corrections for the computed values of theobservable and partial derivatives of the computed values of theobservables with respect to the solve-for-parameter vector-q. TheODP or any other program which uses its formulation can be used tonavigate a spacecraft anywhere in the solar system. A publication of the JPL Deep Space Communications and NavigationSystem Center of Excellence (DESCANSO), Formulation for Observedand Computed Values of Deep Space Network Data Types for Navigationis an invaluable resource for graduate students of celestialmechanics or astrodynamics because it: * features the expertise of today's top scientists * places the entire program Regres formulation in an easy-to-accessresource * describes technology which will be used in the next generation ofnavigation software currently under development 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 conveying state-of-the-art knowledge in key technologies.
