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.

It was a proud moment in the earth's history, when twenty-four dedicated volunteers set off, on that bright summer morning in 1993, to conquer the vastnesses of inter-stellar space. They did not hope to accomplish their Herculean task in the meagre span of human life. It was their descendants who would walk out onto the as yet undiscovered, planets of the alien stars... or so they dreamed. There were dire perils ahead of them. Damage to their engines, radio-activity the invisible killer, space madness and the failure of the life giving hydroponic tanks which supplied their oxygen. Yet the worst enemy of all was the enemy within themselves. The human failure of men and women, locked in the close confines of the Star Ship. Then there was the Alien Ship... Friend or foe?... Saviour or destroyer?

These proceedings include most of the papers presented at the lAG Sympo sium GPS Trends in Precise Terrestrial, Airborne, and Spacebome Appli cations held in July 1995 during the XXI-th IUGG General Assembly in Boulder, Colorado. The symposium was jointly organized by the lAG and the International Union of Surveys and Mapping (IUSM). The symposium was divided into four sessions, namely (1) The International GPS Service for Geodynamics (IGS) and other Permanent Networks, (2) Spaceborne Applications of the GPS, (3) Kinematic Applications of the GPS, and (4) The GPS and its Relations to Geophysics. The main purpose was to give an overview of the state of the art in 1995 of the applications of the GPS to geodynamics, geodesy, surveying, and navi gation. The call for papers generated a flood of originally more than 70 abstracts; quite a few could be redirected to other symposia, but still 56 papers found their way into these proceedings. We thus conclude that the volume gives a rather complete overview of GPS Trends in Precise Terrestrial, Airborne, and Spacebome Applications in the year 1995.

This book discusses in detail the science and morphology of powerful hurricane detection systems. It broadly addresses new approaches to monitoring hazards using freely available images from the European Space Agency’s (ESA’s) Sentinel-1 SAR satellite and benchmarks a new interdisciplinary field at the interface between oceanography, meteorology and remote sensing. Following the launch of the first European Space Agency (ESA) operational synthetic aperture radar satellite, Sentinel-1, in 2014, synthetic aperture radar (SAR) data has been freely available on the Internet hub in real-time. This advance allows weather forecasters to view hurricanes in fine detail for the first time. As a result, the number of synthetic aperture radar research scientists working in this field is set to grow exponentially in the next decade; the book is a valuable resource for this large and budding audience.

Synthetic Aperture Radar is a topic of great interest all over the world. SAR remote sensing is being used for Earth observation, geophysical applications and environmental monitoring. This book covers SAR theory, SAR data processing, and SAR applications using ALOS/PALSAR data. Particularly of interest are topics such as calibration, interferometry and SAR imaging of forested regions, disaster monitoring and the effects of climate change. It explains in detail the JAXA SAR products; large scale SAR imaging and SAR mosaicking. This book is the result of the authors’ 30 year experience in SAR imaging.

A flight computer functional executive design for the reusable shuttle is presented. The design is given in the form of functional flowcharts and prose description. Techniques utilized in the regulation of process flow to accomplish activation, resource allocation, suspension, termination, and error masking based on process primitives are considered. Preliminary estimates of main storage utilization by the Executive are furnished. Conclusions and recommendations for timely, effective software-hardware integration in the reusable shuttle avionics system are proposed. -- V. I. The computer executive functional system design concepts derived from study of the Space Station/Base are presented. Information Management System hardware configuration as directly influencing the executive design is reviewed. The hardware configuration and generic executive design requirements are considered in detail in a previous report (System Configuration and Executive Requirements Specifications for Reusable Shuttle and Space Station/Base, 9/25/70). This report defines basic system primitives and delineates processes and process control. Supervisor states are considered for describing basic multiprogramming and multiprocessing systems. A high-level computer executive including control of scheduling, allocation of resources, system interactions, and real-time supervisory functions is defined. The description is oriented to provide a baseline for a functional simulation of the computer executive system. -- V. II. THis report investigates the executive routine primitives and process control for spaceborne computer functional design specification -- V. III.
