Global Positioning System

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.

If you're looking for an up-to-date, easy-to-understand treatment of the GPS (Global Positioning System), this one-of-a-kind resource offers you the knowledge you need for your work, without bogging you down with advanced mathematics. It addresses all aspects of the GPS, emphasizes GPS applications, examines the GPS signal structure, and covers the key types of measurement being utilized in the field today.

Accompanying CD-ROM contains a number of GPS data sets from several sites. A set of homework problems requires the student to write simple MATLAB code to analyze these data.

An updated guide to GNSS and INS, and solutions to real-world GPS/INS problems with Kalman filtering Written by recognized authorities in the field, this second edition of a landmark work provides engineers, computer scientists, and others with a working familiarity with the theory and contemporary applications of Global Navigation Satellite Systems (GNSS), Inertial Navigational Systems (INS), and Kalman filters. Throughout, the focus is on solving real-world problems, with an emphasis on the effective use of state-of-the-art integration techniques for those systems, especially the application of Kalman filtering. To that end, the authors explore the various subtleties, common failures, and inherent limitations of the theory as it applies to real-world situations, and provide numerous detailed application examples and practice problems, including GNSS-aided INS, modeling of gyros and accelerometers, and SBAS and GBAS. Drawing upon their many years of experience with GNSS, INS, and the Kalman filter, the authors present numerous design and implementation techniques not found in other professional references. This Second Edition has been updated to include: GNSS signal integrity with SBAS Mitigation of multipath, including results Ionospheric delay estimation with Kalman filters New MATLAB programs for satellite position determination using almanac and ephemeris data and ionospheric delay calculations from single and dual frequency data New algorithms for GEO with L1 /L5 frequencies and clock steering Implementation of mechanization equations in numerically stable algorithms To enhance comprehension of the subjects covered, the authors have included software in MATLAB, demonstrating the working of the GNSS, INS, and filter algorithms. In addition to showing the Kalman filter in action, the software also demonstrates various practical aspects of finite word length arithmetic and the need for alternative algorithms to preserve result accuracy.

These two-volumes explain the technology, performance, and applications of the Global Positioning System (GPS). The books are the only of their kind to present the history of GPS development, the basic concepts and theory of GPS, and the recent developments and numerous applications of GPS. Each chapter is authored by an individual or group of individuals who are recognized as leaders in their area of GPS. These various viewpoints promote a thorough understanding of the system and make "Global Positioning System: Theory and Applications" the standard reference source for the GPS. The two volumes are intended to be complementary. Volume I concentrates on fundamentals and Volume II on applications. They are recommended for university engineering students, practicing GPS engineers, applications engineers, and managers who wish to improve their understanding of the system.

All the expert guidance you need to understand, build, andoperate GPS receivers The Second Edition of this acclaimed publication enablesreaders to understand and apply the complex operation principles ofglobal positioning system (GPS) receivers. Although GPS receiversare widely used in everyday life to aid in positioning andnavigation, this is the only text that is devoted to completecoverage of their operation principles. The author, one of theforemost authorities in the GPS field, presents the material from asoftware receiver viewpoint, an approach that helps readers betterunderstand operation and that reflects the forecasted integrationof GPS receivers into such everyday devices as cellular telephones.Concentrating on civilian C/A code, the book provides the tools andinformation needed to understand and exploit all aspects ofreceiver technology as well as relevant navigation schemes: Overview of GPS basics and the constellation of satellites thatcomprise the GPS system Detailed examination of GPS signal structure, acquisition, andtracking Step-by-step presentation of the mathematical formulas forcalculating a user's position Demonstration of the use of computer programs to run keyequations Instructions for developing hardware to collect digitized datafor a software GPS receiver Complete chapter demonstrating a GPS receiver following asignal flow to determine a user's position The Second Edition of this highly acclaimed text has beengreatly expanded, including three new chapters: Acquisition of weak signals Tracking of weak signals GPS receiver related subjects Following the author's expert guidance and easy-to-follow style,engineers and scientists learn all that is needed to understand,build, and operate GPS receivers. The book's logical flow frombasic concepts to applications makes it an excellent textbook forupper-level undergraduate and graduate students in electricalengineering, wireless communications, and computer science.
