Abstract In accordance with the problem of failure tracking in coherent composite code tracking loop leaded by greater carrier phase tracking error, a non-coherent tracking loop is proposed in this paper. The methods of constructing composite Pseudo-Noise (PN) code sequences with Binary Offset Carriermodulation (BOC) modulation and the correlation properties are given. The non-coherent discriminator and the loop filter of the tracking loop and the analysis of the loop tracking performance are also presented. The analysis and simulation show that the design of PN code tracking loop can work effectively with the existence of the carrier phase tracking error and also gives a good tracking performance.
