摘要/Abstract

摘要： 信号体制是卫星导航系统性能的决定性因素之一,是系统设计和升级必须解决的关键技术.分析了国外先进卫星导航信号体制的设计思想,汇总了GPS和Galileo信号体制设计的最新成果,解读了卫星导航信号体制的演进过程,并从频率结构设计、码速率选择、信号波形设计、扩频码设计、信息速率选择和信道编码设计六个方面挖掘了现代导航信号体制的设计思想.在总结信号体制设计理念的基础之上,提出了信号体制的发展方向.

Abstract: Signal structure is one of the decisive factors for satellite navigation systems and is one of the key technologies which must be resolved during system design and upgrading process.This paper studies design principles of the foreign advanced satellite navigation signal structure and summarizes the latest results of the GPS and Galileo signal structure design.By describing the evolution of satellite navigation signals,modern global navigation satellite systems(GNSS) signal design methods are introduced in six aspects including frequency structure design,code rate selection,signal waveform design,spreading code design,data rate selection and channel coding design.Based on these design concepts,the GNSS signal structure development direction is presented.
