Accuracy can be ascertained in a matter of meters. In advanced forms of GPS, the measurements are even more accurate to as close as centimeters.

Re: GPS Satellites
These days, the technology to make these satellites have been that sophisticated to make them rather small with only a few necessary integrated circuits. That is why it is so economical to build one of these.
