小区域地图GPS导航仪设计与实现

Design and Implementation of Small Area Maps GPS Navigators

为便于人们在旅游区、大型游乐城等无交通路线易迷失的小区域游览,文中以宏晶8位单片机为核心,通过串口通信接收GPS模块信息,实现了地理坐标与自制地图对应关系的小区域导航仪。该导航仪应用测试表明,在5-10米精度范围内对于大建筑物定位准确,能够用于自制小区域地图的导航。

In order to facilitate touring in some small area,such as tourist area,large-scale amusement house,where without traffic routes and easily lost,in this paper taking the STC 8-bit Single-Chip Microcomputer as the core,through serial communication receiving GPS module information,realized the corresponding relationship of small area navigator between geographic coordinates and self-made map.The navigator application test indicated that the navigator for buildings can fix an accurate position in 5-10 meters accuracy range and can be used in self-made small area map navigation.
