Uncertainties in GPS Positioning: A Mathematical Discourse describes the calculations performed by a GPS receiver and the problems associated with ensuring that the derived location is a close match to the actual location. Inaccuracies in calculating a location can have serious repercussions, so this book is a timely source for information on this rapidly evolving technology.
- Covers how a GPS receiver works and how the earth is modeled so position data can be calculated
- Discusses the different signals and clock speeds of the satellites, the receivers, and sources of inaccuracy
- Examines how the errors are distributed in the data and provides examples

Alan Oxley
Alan Oxley is Professor of Computer and Information Sciences at Universiti Teknologi PETRONAS in Malaysia. Alan is an all-rounder in Computer Science and has written numerous academic articles and chapters. Recently he was awarded a research stipend by the IBM Center for the Business of Government. The research led to the publication of the report entitled A Best Practices Guide for Mitigating Risk in the Use of Social Media. A considerably more expansive exposition of the topic is presented in this book.
