This thoroughly updated third edition of an Artech House bestseller brings together a team of leading experts providing a current and comprehensive treatment of global navigation satellite systems (GNSS) that readers won’t find in other resources. Packed with brand new material, this third edition includes new chapters on the system engineering details of GPS, European Galileo system, Chinese Beidou systems, GLONASS, and regional systems, such as Quasi–Zenith Satellite System (QZSS) and Navigation with Indian Constellation (NavIC). Readers also find new coverage of GNSS receivers, disruptions, errors, stand-alone GNSS performance, differential and precise point positioning. This single-source reference provides both a quick overview of GNSS essentials and an in-depth treatment of advanced topics and explores all the latest advances in technology, applications, and systems. Readers are guided in the development of new applications and on how to evaluate their performance. It explains all the differential GNSS services available to help decide which is best for a particular application. The book discusses the integration of GNSS with other sensors and network assistance. Readers learn how to build GNSS receivers and integrate them into navigational and communications equipment. Moreover, this unique volume helps determine how technology is affecting the marketplace and where best to invest in a company’s resources.

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.

This, the second edition of the hugely practical reference and handbook describes kinematic, static and dynamic Global Positioning System theory and applications. It is primarily based upon source-code descriptions of the KSGSoft program developed by the author and his colleagues and used in the AGMASCO project of the EU. This is the first book to report the unified GPS data processing method and algorithm that uses equations for selectively eliminated equivalent observations.

The Navstar Global Positioning System (GPS) is being financed by military dollars, but the precise navigation signals it broadcasts are available free of charge to anyone, anywhere. Over the next ten years sponsors of Navstar navigation will be investing an estimated

GPS and GNSS Technology in Geosciences offers an interdisciplinary approach to applying advances in GPS/GNSS technology for geoscience research and practice. As GPS/GNSS signals can be used to provide useful information about the Earth’s surface characteristics and land surface composition, GPS equipment and services for commercial purposes continues to grow, thus resulting in new expectations and demands. This book provides case studies for a deeper understanding of the operation and principles of widely applied approaches and the benefits of the technology in everyday research and activities. Presents processing, methods and techniques of GPS/GNSS implementation that are utilized in in-situ data collection in design and systems analysis Offers an all-inclusive, critical overview of the state-of-the-art in different algorithms and techniques in GPS/GNSS Addresses both theoretical and applied research contributions on the use of this technology in a variety of geoscience disciplines

All the expert guidance you need to understand, build, and operate GPS receivers The Second Edition of this acclaimed publication enables readers to understand and apply the complex operation principles of global positioning system (GPS) receivers. Although GPS receivers are widely used in everyday life to aid in positioning and navigation, this is the only text that is devoted to complete coverage of their operation principles. The author, one of the foremost authorities in the GPS field, presents the material from a software receiver viewpoint, an approach that helps readers better understand operation and that reflects the forecasted integration of GPS receivers into such everyday devices as cellular telephones. Concentrating on civilian C/A code, the book provides the tools and information needed to understand and exploit all aspects of receiver technology as well as relevant navigation schemes: Overview of GPS basics and the constellation of satellites that comprise the GPS system Detailed examination of GPS signal structure, acquisition, and tracking Step-by-step presentation of the mathematical formulas for calculating a user's position Demonstration of the use of computer programs to run key equations Instructions for developing hardware to collect digitized data for a software GPS receiver Complete chapter demonstrating a GPS receiver following a signal flow to determine a user's position The Second Edition of this highly acclaimed text has been greatly 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 from basic concepts to applications makes it an excellent textbook for upper-level undergraduate and graduate students in electrical engineering, wireless communications, and computer science.

"One of the most mesmerizing and exhilarating, yet alarming modern technology books…an extraordinary tale." —Gillian Tett, Financial Times Pinpoint tells the fascinating story of a hidden system that touches nearly every aspect of modern life. Tracking the development of GPS from its origins as a bomb guidance system to its present ubiquity, Greg Milner examines the technology’s double-edged effect on the way we live, work, and travel. Savvy and original, this sweeping scientific history offers startling insight into how humans understand their place in the world.
