摘要
从手持GPS定位仪的二进制输出记录中提取出厘米级的高分辨率位置数据,并使用多次平均值测量、位置后差分校正的方法,使轻便、价廉的手持GPS定位仪平面定位误差从数米降低到1 m左右,达到亚米级精度。
The high-resolution position data in the centimeter grade are extracted from the binary output records of the hand-held GPS position indicator, and the multiple average measurement and post-operation position difference correction method are used so as to decrease the planar locating error of the portable and cheap hand-held GPS position indicator from several meters to 1 m or so. Thus the precision of the sub-meter grade can be attained.
