With wave lengths, i assume, being sent up to the satellites. can you talk about how that would affect the calculations? >> right. it's that way shift in the phase form. you must have done well in high school physics. the other example is ambulance. you're standing on a street corner. you hear an ambulance approaching. it's different when it goes past you but you haven't moved and the ambulance's siren hasn't changed. it's how that wave form arrived at your ears and how it was processed. there's a way to measure that time and that wave form and to expect information out of it, which is what th...
