现阶段有许多因素影响着GPS的定位精度,多径效应就是其中之一,特别在城市环境中,它显得尤为严重。论文中给出了改进型Strobe鉴相器方案,在传统型Strobe算法的基础上,结合对不同多径延迟特性的分析,推导出修正项,使其能够在短多径的条件下更好地进行误差估计,完成精确定位。%Multipath is one of the sources that impact the GPS resolution.It is particularly sever in urban environment.An improved strobe correlator is presented in the paper.Based on the traditional strobe algorithm,the different delays of various kinds of multipa
