摘要：
In this paper, the advantages of utilizing Quasi-Zenith Satellite System (QZSS) are discussed. Experiment results show that the GPS L1 complementary signal from QZSS improves the availability of L1 code positioning approximately 1.7 to 2.5 times when it is compared to GPS only L1 code positioning. Furthermore, simulation results of loosely coupled GPS/Low-cost INS (Inertial Navigation Systems) with and without QZSS are shown. From the results, it is concluded that the system with QZSS makes its use as a future lane-navigation system possible by reducing the positioning errors by more than 30 percent compared to the system without QZSS.
