摘要
笔者介绍了以Zarlink公司的GP2015、GP2021芯片组为核心架构,以C6747为相关计算处理器的GPS硬件电路设计,充分考虑了低功耗、高性能及小封装的弹载环境要求;以常用信号捕获算法为基础,给出了GPS定位软件的核心流程框图;最后在完成硬件设计和快捕算法的基础上,进行了导航电文译码检测。
In this paper,a GPS hardware circuit diagram is elaborated,the diagram take the GP2015 and the GP2021 chip set of Zarlink company as the nucleus frame,take C6747 as the related calculator,well considering low-power,high performance and small encapsulation,which are requested in the shell environment;take the familiar arithmetic of signal quickly undertaking as the foundation,it presents the core flow chart of the GPS position software;finally after completing the hardware and the arithmetic designs,an examination of the translating of the navigation code is carried.
