- Michibiki is the first QZSS satellite, which was launched by a H-IIA rocket departing from the Tanegshima in Japan on 11 September, 2010 and now operated successfully. This paper presents the results obtained from processing of the L1 C/A signal transmitted from the QZSS satellite. The acquisition and tracking are performed by the L1 software receiver implemented by ETRI. The signal processing results show that QZSS L1 C/A signal is normally processed through the tracking loop results of FLL, PLL, and DLL, the EPL correlator output, and the C/No output. Finally, the paper demonstrates that the QZSS satellite could be used in the navigation system together with the GPS satellite in Korea.
