A children's book aimed at the 4th to 9th Grade level that explores the many practical aspects and uses of GPS and how it all works. The book starts out with a practical explanation of how location finding works and then translates this to how a GPS satellite and receiver figures your location. The book then continues to show the child reader what goes on and goes in a GPS satellite. Next, the many different ways in which a GPS receiver can be used for such areas as farming, rescue, surveying, smart phones and many more are all explored. The child's imagination is challenged at the "Imagination Station" where they have to think of creative ideas for using GPS now and/or in the future. The kids' minds are also challenged to draw a satellite and include some of the parts they have learned. The book closes with a look at the child's future, asking them what they want to be, explaining how any interest in GPS could give them the possibility of being an engineer, software designer, pilot, seismologist or many more. Big words such as seismologist and meteorologist are broken down and explained so that the child would have added several "big words" to their vocabulary. Finally, a word search and crossword puzzle will allow the reader to search for these new words and concepts and understand them.
