Written for adults, this introduction to GPS from Trimble (a GPS manufacturer) explains GPS in more detail than many grownups can swallow. The animations will interest students, and physics teachers will no doubt find ways to translate the information in ways their students can grasp. The explanation itself is a great "problem solving" example. Lots of info here, but some demos use Flash.
