This is a quick introduction to how GPs technology works. It only takes about seven minutes to read. The last half is some boilerplate about Garmin products, but the first bit about the GPS Satellite network is sort of interesting.
I also remember discussing w/ my dad how the Garmin unit handles north (magnetic and true). This report says the unit just has its own little model of the magnetic fluctuations around the earth.
