An Introduction to GNSS Geodesy and Applications

by Clement A. Ogaja

This volume is the second edition to 2022’s Introduction to GNSS Foundations of Precise Positioning Using Global Navigation Satellite Systems. It serves as an important reference to GNSS beginners as well as seasoned enthusiasts. In this updated edition, author Clement Ogaja focuses on fundamentals and contents that will remain unaffected by rapid changes and data exchange formats, ensuring that the book will remain up to date for years.



The book consists of five chapters. The first covers basic concepts of parameter estimation in GNSS Geodesy. From there, Chapter 2 discusses reference systems in GNSS Geodesy. Chapter 3 moves on to observation models, errors, and biases, and Chapter 4, which is completely new to this second edition, details GNSS data processing workflow and strategies. The book concludes with an applied chapter that details concrete uses of GNSS Geodesy. New appendices that will be especially useful to seasoned users are also featured.
