摘　　要：使用静态局部坐标修正算法绘制小区GPS地图.提出可行性高和易于实现的基于方向值双向法查找近似最短路径,以及基于方向比较和方向记忆的地图匹配方法.设计了嵌入式小区GPS导航系统.实验结果表明,该系统有较好的定位和导航准确度.Through charting a GPS map of an area and using static local positioning correction algorithm, the expense for electronic map is lowered. The value doubledirection method is presented to find the approximate shortest path, and the direction comparison and memory algorithm are used to match maps with high feasibility and easy implementation. A design of a GPS navigation embedded system is discussed. The accuracy of positioning and navigation is increased.
