Ogaja C.A. Applied GPS for Engineers and Project Managers

ASCE Press, 2011. — 222 p.
One of the purposes of this book is to provide guidance to engineers and project managers who wish to incorporate GPS into their projects or research, regardless of their past experience with the technology. While there is not a one-sizefits- all approach to using GPS, certain key concepts and methods are common to any project. Using GPS in a project requires more than just getting a GPS receiver, turning it on, and pushing a few buttons. Decisions must be made about the level of accuracy required to address the project or research problem. For example, is 1-cm accuracy needed or is 1-m accuracy sufficient? How will the data be collected and analyzed or displayed? Is a 10-Hz data logging rate needed or is 1-Hz sufficient? These are just some of the questions to be addressed in an engineering perspective. The answer will influence the types of receivers purchased, the data collection and management approach, as well as the GPS error correction methods applied. There is great value in asking these questions and important lessons to take away from this book.
