The Global Positioning System (GPS) is a satellite-based navigation system that was originally designed for the U.S. military. However, the number of civilian GPS users now exceeds the military users, and many commercial markets have emerged. This book identifies technical improvements that would enhance military, civilian, and commercial use of the GPS. Several technical improvements are recommended that could be made to enhance the overall system performance.

The Global Positioning System (GPS), which provides position, navigation, and timing data to users worldwide, has become essential to U.S. national security and a key tool in an expanding array of public service and commercial applications. The Air Force is in the process of modernizing GPS. In light of the importance of GPS, the modernization effort, and international efforts to develop new systems, the auditor undertook a broad review of GPS. Specifically, she assessed progress in: (1) acquiring GPS satellites; (2) acquiring the ground control and user equipment necessary to leverage GPS satellite capabilities; and (3) evaluated coordination among fed. agencies and other org. to ensure GPS missions can be accomplished.

From stars to terrestrial networks and satellites From outdoors to indoors From ancient to future applications From techniques to technologies . . . The field of radionavigation signals and systems has seen significant growth in recent years. Satellite systems are very efficient, but owing to their limited exposure and/or availability in some environments, they do not cover the whole spectrum of applications. Thus, many other positioning techniques are being developed. Now, Global Positioning presents an overview of the strengths and weaknesses of various systems with a specific emphasis on those that are satellite-based. Beginning with a description of the evolution of positioning systems, the book provides detailed coverage of the three main Global Navigation Satellite System (GNSS) constellations, discusses how to cope with indoor positioning, defines development activities and commercial positioning, and proposes a vision for the future of the field. Special features of the book include: Exercises to test and challenge the reader's understanding Direct comparison between constellations and other positioning systems Mathematical content kept to a minimum in order to maximize accessibility and readability Descriptions of European and U.S. discussions for Galileo Historical aspects and links between the distant past and current systems Footnotes that provide hints and comments to the reader At a time when the positioning domain is experiencing such immense transformation, it is vital to have a solid understanding of the fundamental principles, current tech-nologies, and future improvements that will help estimate the performance and limita-tions of existing systems. Global Positioning fills an important need for professionals and students in a variety of fields who want a complete and authoritative overview of global positioning techniques.

The only comprehensive guide to Kalman filtering and itsapplications to real-world GPS/INS problems Written by recognized authorities in the field, this book providesengineers, computer scientists, and others with a workingfamiliarity with the theory and contemporary applications of GlobalPositioning Systems (GPS), Inertial Navigational Systems, andKalman filters. Throughout, the focus is on solving real-worldproblems, with an emphasis on the effective use of state-of-the-artintegration techniques for those systems, especially theapplication of Kalman filtering. To that end, the authors explorethe various subtleties, common failures, and inherent limitationsof the theory as it applies to real-world situations, and providenumerous detailed application examples and practice problems,including GPS-aided INS, modeling of gyros and accelerometers, andWAAS and LAAS. Drawing upon their many years of experience with GPS, INS, and theKalman filter, the authors present numerous design andimplementation techniques not found in other professionalreferences, including original techniques for: * Representing the problem in a mathematical model * Analyzing the performance of the GPS sensor as a function ofmodel parameters * Implementing the mechanization equations in numerically stablealgorithms * Assessing computation requirements * Testing the validity of results * Monitoring GPS, INS, and Kalman filter performance inoperation In order to enhance comprehension of the subjects covered, theauthors have included software in MATLAB, demonstrating theworkings of the GPS, INS, and filter algorithms. In addition toshowing the Kalman filter in action, the software also demonstratesvarious practical aspects of finite word length arithmetic and theneed for alternative algorithms to preserve result accuracy. An Instructor's Manual presenting detailed solutions to all theproblems in the book is available from the Wiley editorialdepartment.

This book is dedicated to Dr. Benjamin William Remondi for many reasons. The project of writing a Global Positioning System (GPS) book was con ceived in April 1988 at a GPS meeting in Darmstadt, Germany. Dr. Remondi discussed with me the need for an additional GPS textbook and suggested a possible joint effort. In 1989, I was willing to commit myself to such a project. Unfortunately, the timing was less than ideal for Dr. Remondi. Therefore, I decided to start the project with other coauthors. Dr. Remondi agreed and indicated his willingness to be a reviewer. I selected Dr. Herbert Lichtenegger, my colleague from the Technical University Graz, Austria, and Dr. James Collins from Rockville, Maryland, U.S.A. In my opinion, the knowledge of the three authors should cover the wide spectrum of GPS. Dr. Lichtenegger is a geodesist with broad experience in both theory and practice. He has specialized his research to geodetic astron omy including orbital theory and geodynamical phenomena. Since 1986, Dr. Lichtenegger's main interest is dedicated to GPS. Dr. Collins retired from the U.S. National Geodetic Survey in 1980, where he was the Deputy Director. For the past ten years, he has been deeply involved in using GPS technology with an emphasis on surveying. Dr. Collins was the founder and president of Geo/Hydro Inc. My own background is theoretically oriented. My first chief, Prof. Dr. Peter Meissl, was an excellent theoretician; and my former chief, Prof. Dr.mult. Helmut Moritz, fortunately, still is.

The GPS provides positioning, navigation, and timing (PNT) data to users worldwide. The U.S. Air Force (AF) is in the process of modernizing the system. But, it is uncertain whether the AF could acquire new satellites in time to maintain GPS service without interruption. This report assesses: (1) the status of AF efforts to deliver new GPS satellites, the avail. of the GPS constellation, and the potential impacts on users if the constellation avail. diminishes below its committed level of performance; (2) efforts to acquire the GPS ground control and user equipment necessary to leverage GPS satellite capabilities; (3) the GPS interagency requirements process; and (4) coord. of GPS efforts with the internat. PNT community. Illus. This is a print on demand report.

Space geodesy has evolved in the last twenty years into one of the most exciting disciplines in the earth sciences. This development is due to a large extent to the versatility of applications provided by the radio interferometric technique called Global Positioning System or GPS. Appropriately, Symposium 102: Global Positioning System: An Overview was held at the 125th Anniversary Meeting of the International Association of Geodesy in August, 1989. A broad review of GPS geodesy, achievements to date and the prospects for future study and application was presented. Papers included in this volume are grouped as follows: - Static and Geodynamic Positioning; - Orbit Determination Optimization and Design Dynamic; - Kinematic GPS/INS Radio Tracking Systems A useful reference for any researcher or student of space geodesy.

Global Positioning for Financial Services is a broad-based examination of the changes occurring in financial services. The forces of privatization and securitization are but two of the factors that are changing the way financial services are delivered. Technology has enabled direct sale of securities to ultimate investors in ways that have not been possible until now. Regulators must adjust their perceptions of risk and reward to maintain safe systems. Astute industry participants must have a clear understanding of these dynamics in order to develop effective strategies for the future.
