> One of those additional complexities worth mentioning is the velocity of a satellite relative to the observer on Earth. Due to Doppler effect this changes the frequency of the signal as seen by the receiver. To correctly acquire the signal the device has to tune in on both the time offset and the appropriate frequency. Does anyone know of a diagram that shows this?
