1、基于单片机的GPS导航装置的设计摘要GPS是英文GlobalPositioningSystem(全球定位系统)的简称。GPS技术在军事、通讯、勘探、气象、导航、大地测量等众多学科领域得到了极其广泛的应用,推动了科学技术的飞速发展,也丰富了人们的科学文化生活。因其具有性能好、精度高、应用广的特点,作为先进的测量手段和新的生产力,已经融入到了国民经济建设国防建设和社会发展的各个应用领域。本次设计采用GPS模块(M-87),基于单片机STC89C52来实现GPS定位信息显示系统。本设计详细介绍了一种成本低廉,操作简单的经济型GPS
2、定位系统的设计方案。本方案基于STC89C52单片机,LOLUXM-87,12864液晶显示屏等硬件,应用C语言进行编程,可以完成GPS信息的提取,显示时间、经度、纬度等信息。分别从硬件设计和软件设计等方面对其做了详细的阐述,并结合硬件的特点研究了STC89C52单片机如何与GPS接收模块实现串行通信,该系统是根据GPS模块数据输出基本原理设计而成的。这种设计精度高、体积小、携带方便,可以实现全天候实时定位导航。关键词:GPS,单片机,LOLUXM-87,12864液晶屏DesignofGPSpositioningsyste
