Crosstown Traffic: How your GPS works

I saw this over on the Adafruit blog today.  I don’t know why they called it “How Does Your Smartphone Know Your Location?“, to me it explains how any GPS receiver works.  But maybe I’m the only person left that uses a GPS navigator that is separate from my cellphone.  I don’t know.  But it’s interesting.  Especially in how it describes the workings of an atomic clock.
