摘要
随着信息技术的发展,定位、定向日益广泛地应用于部队快速机动,成为处理突发事件必不可少的手段和工具。利用现代高精度传感器,实现快速定位、准确定向,为部队机动提供可靠保障。本文介绍基于PC-104模块,采用双串口中断技术,利用磁偏角修正的便携式定位定向装置设计实现。通过GPS采集地理信息,利用经纬度计算磁偏角,与电子罗盘数据进行运算,得到准确的定向数据。达到定位、定向的目的。
With the development of IT,positioning and directional devices are used more widely on the troop sharply motorment and become the necessary tools to deal with emergency.With the high sensitivity sensors ,we can bring out rapidly positioning and precisely directioning device to provide safeguard for the troop moving.This paper discussed the design and implement of portable positioning and directional device using interrupt techniques and compensation with declination based on PC-104 module. The geographical informat ion is read from-the GPS,then the declination is computed using the longitude and latitude,last,the dictional information from the digital compass pluses the declination,the dictional data is obtained,So the purpose of rapid positioning and pricise directional is reached.
