摘　　要：考虑新扩频方式、新调制方式以及频率共享等特性要求,单用途的同步接收已不能满足需要。以GPS系统及Galileo系统中的L1,L5频段信号为例,在对其信号机理、特性进行研究的基础上,重点通过相应的控制策略及数据处理方法,对通道、积累时间、处理方式等进行合理选取,从而达到对多模信号同步接收的目的。进一步的仿真实验表明了此方法的可行性、合理性及有效性。Considering the new spread spectrum technology, the new signal modulation system and the frequency sha-ring characteristic, the synchronization method of single purpose haven＇t meet the need. Based on the studying of signal mechanism and characteristic of the L1 and L5 frequency signals in GPS and Galileo system, the control technology and data process method were weighty studied, the channels, accumulate time and process method were rationally choiced. Therefore, the purpose of multi-mode signals receiving and synchronization was gained, furthermore the simulation and performance test were implemented, providing the feasibility, rationality and validity of the method.
