大学实验室开放项目成果（论文）题目：基于单片机的GPS定位系统1 摘要全球定位系统（ GPS）是美国研发的第二代卫星无线电导航系统。其目的是在全球范围内对地面和空中目标进行准确定位和监测。它能为用户提供全球性、全天候、连续、实时、高精度的三维坐标、三向速度和时间信息。随着GPS的民用化与成本的降低，已经走入了人们的日常生活中，很多手机、PDA 等手持设备都配备了 GPS功能。本文主要研究GPS 的定位原理与技术，单片机的编程及其应用，液晶屏的功能及其实现方法本控制系统主要完成接受数据、时间显示、经度显示、纬度显示等常规功能。此方案基于单片机、GPS模块和 12864 液晶显示屏等硬件 , 并应用 C语言实现了 GPS信号的提取、显示及基本的键盘控制操作等。经过实践测试 , 这种接收机可以达到基本GPS信息的接收以及显示， 可以做到体积小、 精度高、 连续导航， 本设计在测控领域的应用开发中具有一定的实用价值和借鉴价值。关键词 ：GPS定位，液晶显示，单片机2 Abstract Global Positioning System (GPS) is a U.S. research and development of the second generation satellite radio navigation system. Its purpose is worldwide on the ground and air targets for accurate positioning and monitoring. It provides users with a global, all-weather, continuous, real-time, high-precision three-dimensional coordinates, three velocity and time information. With the GPS civilian and cost reduction, has been into people's daily life, many cell phone, PDA and other handheld devices are equipped with GPS. This paper studies the principles and techniques of GPS positioning, microcontroller programming and its application, the function of the LCD screen and its implementation method of the control system is mainly complete to accept data, time display, display longitude, latitude, display and other regular features. This scheme is based on single-chip, GPS module and 12,864 LCD screen and other hardware, and apply the C language implementation of the GPS signal extraction, display an...
