When GPS receiver measures the propagation distance from satellites to the receiver, it can usually obtain two basic measurement values, code phase and carrier phase. Although the precision of carrier phase measurement is higher than that of code phase measurement, there exists the integer ambiguity problem, whose cost is much higher than that of using code phase technique in practical application. Therefore, based on the phase stripe technique, a high-precision code phase measurement method was proposed. On the basis of the traditional code tracking loop, the high-precision code phase measurement value is obtained by extracting the frequency of the phase stripes of the cross-correlation power spectrum, so as to assemble a high-precision code pseudo-range. Simulation results show that the precision of code phase measurement is about 0.37 m when the SNR is -15 dB, which is better than the tracking accuracy of 1.82 m under the same condition of traditional delay lock loop. At the same time of obtaining the higher-precision code phase measurements, the integer ambiguity of the carrier phase does not need to be solved, which has research significance and application value for improving the GPS positioning precision.
