基于MCU的手持GPS接收机的设计

Design of Portable GPS Receiver Based on MCU

全球定位系统(GPS)的发展给导航领域带来了一场革命。详细介绍了一种手持式GPS接收机的设计方案。此方案基于单片机、GPS-OEM板和液晶显示屏等硬件,并从单片机系统部分和GPS解码导航电文部分两个方面讨论了方案的软件设计。经过实践测试,这种接收机可以达到基本GPS信息接收以及显示。它可以做到体积小、成本低、可广泛应用于个人野外旅游探险、出租汽车定位及海上作业等领域。

GPS plays an important role in navigation field, a design scheme of portable GPS receiver is introduced which is based on single chip computer,GPS- OEM and LCD. The software design in single chip computer system and GPS decoding navigation data message is discussed. By practical measurement,the receiver can achive GPS information receive and display. It has small size and low cost, can be used in wild adventure tourism, taxi positioning and operations at sea.
