From Booklist
GPS (the Global Positioning System) can locate an airplane "accurately within a few feet in three dimensions--latitude, longitude and altitude." This is an introduction and guide to GPS. Clarke, who says the system is so simple a child could use it, explains GPS's history and theory, the "hardware user receivers and government-provided space-based and land-based equipment needed to utilize" it, and GPS applications for both civilian and military purposes. He also discusses the system's incredible accuracy, which "exceeds that to which most maps can be read," and the national defense security system that is in place to protect GPS. Parts of the book are technical, so that reader familiarity with aeronautic and navigation terminology will be helpful. Its historical component, however, makes this an engaging book for those interested in the history and development of aeronautics and navigation as well as those who fly.
