Synopsis

Introduction to GNSS Geodesy is a concise reference for beginners and experts in GNSS-based satellite geodesy. It covers all of the important concepts in almost a third of the space of the other GNSS books. Th e book begins with a case study in Augmented Reality to set the stage for what is to come and then moves on to the key elements of GNSS geodesy that make accurate and precise geopositioning possible. For example, it is important to understand the geodetic reference systems and the associated GNSS data processing strategies that enable both accurate and high-precision geopositioning. Chapter 2 gives an overview of GNSS constellations and signals, highlighting important characteristics. Chapter 3 then introduces reference systems in geodesy, covering such topics as time systems, geodetic datums, coordinate systems, coordinate conversions and transformations, and International Terrestrial Reference Frame. Th is lays the framework for the rest of the book. 

Chapters 4 and 5 dig deep into mathematical formulation of GNSS parameter estimation and observation models. All the concepts are presented clearly and concisely, with diagrams to assist reader comprehension. Chapter 6 describes Continuously Operating Reference Station (CORS) networks and their role in geodesy and definition of reference frames. Various global and regional CORS networks are presented in this section. Th e chapter also covers GNSS data and common formats such as RINEX and RTCM. Chapter 7 introduces the whole cycle of GNSS data processing, including preprocessing, ambiguity fixing, and solution reprocessing methods as commonly used in both epoch solutions and time series data. Th e book concludes with appendices on orbit modelling, GNSS linear combinations, application examples, and an example linear model.

About this title

About the Author

Dr. Clement A. Ogaja has worked in various capacities as a professor, researcher and geodesist in the United States, Australia, and Kenya. He received a B.Sc. in Surveying from the University of Nairobi in 1997 and a Ph.D. in Geomatics Engineering from UNSW Sydney, Australia, in 2002. Prior to joining NOAA’s NGS as a geodesist, he was a GNSS systems specialist at Topcon Positioning Systems, and prior to that, he was a professor at California State University in Fresno from 2007 to 2013 where he taught courses in satellite geodesy, geopositioning, project design, engineering math and computer programming. In addition to his three books, "Geomatics Engineering: A Practical Guide to Project Design", "Applied GPS for Engineers and Project Managers" and "Introduction to GNSS Geodesy", he is author and co-author of several research papers published in international scientific journals and conference proceedings.

From the Back Cover

<p><b>Introduction to GNSS Geodesy</b> is a concise reference for beginners and experts in GNSS-based satellite geodesy. It covers all the important concepts in almost a third of the space of the other GNSS books. The author hopes that by starting off with a use case in Augmented Reality, the reader is inspired to learn, in Part II, the key elements of GNSS geodesy that makes accurate and precise geopositioning possible. For example, it is important to understand the geodetic reference systems and the associated GNSS data processing strategies that enable both accurate and high precision geopositioning. Chapter 2 gives an overview of GNSS constellations and signals, highlighting the important characteristics. Chapter 3 introduces reference systems in geodesy, which lays the framework for the rest of the book. It covers topics such as time systems, geodetic datums, coordinate systems, coordinate conversions and transformations, and International Terrestrial Reference Frame. Chapters 4 and 5 dig deep into mathematical formulation of GNSS parameter estimation and observation models. All the concepts are presented clearly, concisely and are easy to follow. Diagrams help to comprehend the topics. Chapter 6 describes an important topic of Continuously Operating Reference Station (CORS) networks and their role in geodesy and definition of reference frames. Various global and regional CORS networks are presented in this section. The chapter also covers GNSS data and the common formats such as RINEX and RTCM. Chapter 7 introduces the whole cycle of GNSS data processing, including preprocessing, ambiguity fixing, and solution reprocessing methods as commonly used in both epoch solutions and time series data.
