My car has it, nowadays every smartphone has it. But what's actually the math behind GPS (GLONASS) technique?
I vaguely know that there is some nonlinear system of equations that needs to be solved to get the 3 coordinates of your location. But what are the details and how is the computation efficiently done (in hard or software)?
Not sure what the result of this project will be. It could be some kind of paper or wiki page to summarize what I've found, a program illustrating different computational approaches to solve the underlying problem or even an Android app to make use of some hardware for GPS.
