摘要
提高GPS的定位精度、延长手持设备的工作时间,是各移动GPS应用行业迫切需要解决的问题。采用基于最小二乘法的数据预处理算法对接收到的GPS数据粗差探测和剔除,提高GPS的定位精度,并利用多线程技术,对手持GPS模块的开启、关闭进行控制,以延长手持设备的工作时间。经实际验证,取得了不错的效果。
How to improve the orientation precision of GPS and extend the working hours of portable devices becomes the focus in the application field of GPS. In this paper, we utilized the arithmetic process the GPS data, which based least square method, to improve the precision, and introduced muhithreading technology to control the StartEnd of GPS module, which meaning to extend the working hours. In practice, using of the method is perfect.
