定位系统是基于AT89C52和GARMINGPS25LP的定位测量系统。其基本功能可分为单片机对GPS器件的控制以及显示采集的信息两部分-GPS is the acronym for Global Positioning System,the Global Positioning System.Its purpose is on a global scale aerial targets on the ground and accurate positioning and monitoring

实现地图的经度，纬度的缩放，就像GPS一样可以显示放大，缩小-To achieve the map longitude and latitude scale, the same as GPS can display zoom
