Signal simulation and positioning mechanisms for single antenna GPS receiver used in fuse

This paper proposes a positioning method for the GPS receiver used in fuse with single antenna as compared to the traditional multi-antenna mode. For that purpose, the intermediate frequency signal received by the single antenna is modeled and simulated, and a positioning method with partial GPS signals is proposed. Based on the positioning method with partial GPS signals and Kalman filter theory, positioning mechanisms for the GPS receiver used in fuse with single antenna are researched. The simulation result shows that the method can avoid the complicated design and fixing of the multi-antenna needed in traditional GPS receivers used in fuse, can reduce the difficulty of designing the tracking loop, and can also improve the anti-jamming ability in the practical application.
