A GPS receiver listens and compares the different timing signals from the GPS satellites and then uses that information to calculate exactly where on. you arrive at a GPS position error of three metres. Thankfully, the GPS network is.
(In other words, what is your receiver's positioning error?). Satellite clock: GPS position calculations, as discussed above, depend on measuring signal.
So THAT’S why your phone’s GPS is so rubbish: Gadgets track you by ‘scattering points’ randomly which causes devices to overestimate distances by up to 20% –. the on-board clocks of the different GPS satellites causes them to run asynchronously with respect to each other.
