Product Description:
Assisted GPS (A-GPS) has been developed to provide greatly improved capabilities, helping GPS work better and faster in almost any location. Offering a detailed look at all the technical aspects and underpinnings of A-GPS, this unique book places emphasis on practical implementation. The book reviews standard GPS design, helping you understand why GPS requires assistance in the first place. You discover how A-GPS enables the computing of a position from navigation satellites in the absence of precise time a topic not covered in any other book.
Moreover, you learn how to design and analyze a high sensitivity GPS receiver and determine the achievable sensitivity. The book provides detailed worksheets that show how to compute, analyze, and improve the processing gain from the input signal at the antenna to the signal after the correlators. These worksheets are used in the book to generate families of curves that completely characterize receiver sensitivity, parameterized in terms of front end noise figure, coherent and noncoherent integration times. From this work a law of achievable sensitivity is derived and explained in the book.
This cutting-edge volume discusses special forms of assistance data, industry standards for A-GPS, and government mandates for location of mobile phones. You also find coverage of future global navigation satellite systems and how they can be designed specifically for instant-fixes and high sensitivity. The book features numerous tables, worksheets, and graphs that illustrate key topics and provide the equivalent of a technical handbook for engineers who design or use A-GPS.
Summary: Fantastic book on GPS system design
Rating: 5
This is a fantastic book on GPS (& A-GPS). My understanding of GPS system design & performance evaluation grew exponentially after reading this book. I've read a lot of GPS books. They all tend to be extremely theoretical and written with graduate students / researchers in mind. This book bridges the gap between theory & practice and offers incredible insight into the way real-world GPS receivers are designed, as well as the intuitive thinking behind each concept.
I highly recommend this book to anyone seeking a in-depth understanding of GPS principles & practice. I would rate this book in the top 1% of my list of GPS books.
Summary: Great GPS resource
Rating: 5
Well-written, easy to understand GPS book. I like the way the first section of each chapter is written so anyone can understand it, while other sections go deeper.
Summary: The definitive book on AGPS!
Rating: 5
Very detailed and clear explanations of AGPS in all regards. I found this book very useful, and I have already cited it in some of my research projects. I especially appreciate the coarse-time and fine-time acquisition sensitivity curves in Chapter 6. Highly recommended!
Summary: Highly recommendable. AGPS for all levels!
Rating: 5
This is an excellent (and the first one, I believe) book on Assisted GPS. Not only does it cover the technical topics with great depth and rigour but it also dwells on less technical topics surrounding AGPS such as standardisation and future positioning constellations (Glonass, Galileo...). There is a table at the beginning of the book that will guide you to the different sections depending on your background. It proved extremely useful for a marketing professional in the wireless industry such as myself.
Overall, an excellent acquisition.
