GPS Made Simple

This presentation provides a basic understanding of GPS for those trying to learn it for the first time. Although satellite navigation now includes constellations from Europe and Asia, all have enough in common to focus on GPS for introductory discussion. Material was selected and organized with a a learner's perspective in mind. for a "straight-to-the-point" exposition with little or no mathematics and, rather than an extensive bibliography, a few few URLs that can be followed towards a wealth of further sources for those interested.
