The Synchronization Reconfiguration for Compatibility GNSS Signals

A variety of satellite navigation system with cooperative navigation is an important development trend of the future GNSS. Based on the needs of multimode signals, analyze the characteristics of new signals. Furthermore, the reconfiguration strategies of multimode signals are studied. Taking synchronous processing speed, accuracy, resource utilization, complexity or something like these into account, the reconfiguration driving, reconfiguration panning, reconfiguration implementation are designed, and then the reconfiguration overall controlling strategy is formed. The strategy is reasonable, efficient, and reconfigurable for the multimode signals. The feasibility and necessity of multimode satellite navigation signal is supplied by the analysis of multimode signal frequency and multimodality modulation.
