The ranging codes ( c_I ) and ( c_Q ) are not the same as legacy PRN codes. They are derived from a new family of Quadrature Gold codes with cross-correlation (\le 2^-10).
If you own a (or any modern GPS module like the u-blox M8Q), you’ve probably marveled at how it knows your location within seconds. But behind that simple “Position Fixed” blink is a fascinating mathematical model—the GPS Navigation Model .
