An updated instructional handbook describes the Global Position System (GPS) that uses satellites along with a receiver to determine its position anywhere in the world, explains features of the receivers, provides practical examples of their use, offers practical tips on using maps and computer software with a GPS receiver, and details how to navigate with a personal GPS. Original.
While this book is pretty badly out-of-date from a technological standpoint, it's actually got some interesting stuff about GPS use, navigation and general outdoors kind of stuff.
