基于ARM的GPS接收机解码系统设计

本文讨论了基于ARM7的GPS接收机解码系统设计,提出了对GPS全球定位系统定位信息的接收以及对各定位参数数据的提取方法,并给出了系统的硬件电路及软件流程图。通过本设计方法,本系统由单片机控制GPS模块较为精确地计算和显示日期、时间、经度、纬度等卫星信息。详细地介绍了用单片机为主要核心电路设计GPS的硬件设计全过程,并给出了GPS软件设计的基本思路、整体电路的原理、PCB设计图和几个电路使用特殊芯片和使用软件资料,是实用性很强的设计方案。

This article discussed the system design on the base of ARM7 chip, proposed the method of the GPS system＇s infformation＇s receiving and withdrawing of the position parameter data. The article has provided the hardware circtuit and software struct. The system that the single chip computer cotrolling the GPS module can precisely calculate and show the satellite information of date, time, longitude, latitude and so on. This paper introduces chip microcomputer which is used to GPS and give the principle diagram of intelligent GPS. Gave the principle of the whole electric circuit. It can be widely applied and is worthy of spreading.
