Abstract: GNSS L1 band includes several satellite navigation system signals, GPS L1 C/A, L1C, Galileo E1, BeiDou B1C and QZSS L1 providing services. Each system signal uses a different modulation technique and code generation method. GPS L1 C/A in L1 band uses Gold Code generation method, Galileo E1-B uses Memory Code and BeiDou B1C uses Weil Code method. For this research, designed SDR is implemented to process these signals. Signals were collected using commercial equipment. The L1 C/A, E1-B and B1C signals that are available to receive in South Korea are collected. The acquisition and tracking process information, which is difficult to obtain from commercial receivers, was obtained through SDR. The discriminator outputs of processing stage are applied to analyze the performance of each signal. In this paper, the acquisition and tracking performance of GPS L1 C/A, Galileo E1-B and BeiDou B1C signals are compared and analyzed.
