【摘要】 在GPS软件接收机信号跟踪过程中,为了解决传统的八通道GPS跟踪方法耗时较长,提出了一种基于码存储的SGR信号跟踪方法。本文对传统的八通道的GPS码跟踪方法进行了分析与理论介绍,基于传统跟踪方法码产生耗时较多,提出了预存码的方法,并介绍了预存码方法的原理与程序流程,最后对两种方法进行了实验测试,通过传统方法与码存储方法的比较分析与仿真实现,证明了码存储方法能够消除码产生的时间,并且输出导航信息幅值不受影响。更多还原

【Abstract】 In the GPS software receiver signal tracking process,in order to solve the traditional eight-channel GPS tracking time-consuming,it presents a code-based storage SGR signal tracking method.In this paper,the traditional eight-channel GPS code tracking methods are analyzed and theoretical introduction.It based on that traditional tracking methods are more time-consuming,code storage method is proposed,and it introduces the principle of pre-existing code method and procedures for processes.Finally,experimental tests carried out in two ways,through traditional methods and code storage method can eliminate the code generated by time and amplitude of the output navigation information will not be affected.更多还原
