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. The objective of this book is to provide you the reader a complete systems engineering treatment of GNSS. I provide a thorough, in-depth treatment of each topic.

Dedicated chapters cover each system's constellation configuration, satellites, ground control system and user equipment. Detailed satellite signal characteristics are also provided. Recently, I've heard from many engineers that they learned how GPS receivers work from this title. In this title, the design is included, and treatment of receivers is updated and expanded in several important ways.

New material has been added on important receiver components, such as antennas and front-end electronics. The increased complexity of multiconstellation, multifrequency receivers, which are rapidly becoming the norm today, is addressed in detail.

Other added features of this title are the clear step-by-step design process and associated trades required to develop a GNSS receiver, depending on the specific receiver application. This subject will be of great value to those readers who need to understand these concepts, either for their own design tasks or to aid their satellite navigation system engineering knowledge.

To round out the discussion of receivers, updated treatments of interference, ionospheric scintillation, and multipath are provided along with new material on blockage from foliage, terrain, and man-made structures.

The use of PPP techniques has greatly increased in recent years, and the treatment in this title has been expanded accordingly. Marketing projections and the challenge thereof are enumerated and discussion of the major applications is provided. As in the other series, this book is structured such that a reader with a general science background can learn the basics of GNSS. The book begins with the basics of GPS receivers and moves onward to more advanced material.

Each receiver is unique allowing the reader to see how each design solves the same problems. Chapters discuss carrier phase measurements and GPS time and frequency measurements.

The overall text is measurement oriented as opposed to processing the measurements. With a focus on the fundamentals of measurements the reader will be building their intuition for the physical phenomenon at work. Offering a detailed look at all the technical aspects and underpinnings of A-GPS, this unique book places emphasis on practical implementation. 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. Filling a gap in the current literature on the subject, this highly practical resource offers you an in-depth understanding of navigation signal detection and estimation algorithms and their implementation in a software radio.

This unique book focuses on high precision applications for GNSS signals and an innovative RTK receiver concept based on difference correlators. You learn how to develop navigation receivers for top performance using basic algorithms, like correlation and tracking, which can be understood on an intuitive level. Additionally, the book provides you with a theoretical framework for signal estimation and detection that gives you the knowledge you need to make performance assessments without building a receiver.

The theoretical treatment also gives you hints for choosing optimal algorithms for your projects in the field. 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.
