About this course
GPS is a constellation of satellites, a network of ground stations, and a small receiver in your pocket, and this course explains all three parts clearly. You will learn how position is computed by timing and trilateration, how other systems like GLONASS and Galileo join the party, why accuracy varies, and how to get the most reliable fixes from your phone and your dedicated GPS unit.
