Factors Influencing GPS Receiver

Spread spectrum frequency GPS signal determines the quality of the precision of GPS receiver, it is the result from the bit error rate (BER) to judge. Assumes that the baseband processor requires a BER of 10-5, Eb/N0 for BPSK modules will not be less than 9.5dB. Eb/N0 is defined as the concentration of energy per bit to noise ratio. From 9.5dB Eb/N0 remove 43dB processors gain related to the input signal to noise ratio is -33.5dB.
