A-GPS: Assisted GPS, GNSS, and SBAS
Frank Van Diggelen
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 book places emphasis on practical implementation. The book reviews standard GPS design, helping readers understand why GPS requires assistance in the first place. Professionals will 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. This book includes 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.
This volume also discusses special forms of assistance data, industry standards for A-GPS, and government mandates for location of mobile phones.

What Others Have Said
“The rapid penetration of GPS into consumer markets has been sustained in so small measure by developments in Assisted GPS. This timely text provides a comprehensive explanation of this emerging technology. It is a highly readable book, rich in new material such as coarse-time navigation, achievable sensitivity, and initial position from Doppler measurements.”
— Charles R. Trimble, Founder, Trimble Navigation
“The proliferation of Assisted GPS into consumer electronics merited an in-depth explanation of the technology and science behind it. Dr. van Diggelen, an A-GPS authority in the navigation industry, shares his wealth of academic, engineering and field experience with all of us in a truly accessible manner. Warmly recommended to all involved in building location aware products and services.”
— Peter-Frans Pauwels, Co-founder and CTO, TomTom
Assisted GPS is a deep topic, and Frank van Diggelen has skillfully explained everything from the details of coarse-time navigation to the limits of high-sensitivity signal processing. An impressively thorough book that leaves no stone un-turned.

Dr. Van Diggelen has a masterpiece on his hands. He covers the topic of Assisted GPS, which will be a critical technology for a good long time. In every paragraph, his love of teaching shines through. He writes with a snap and cadence seldom found in technical writing. He also includes a “book within a book;” some 80 pages or so can be found at the beginning of the book and each chapter. These essays provide overviews to the more analytical material that follows. Enjoy.
