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.
