摘要
手持GPS未经参数校正时定位精度为80~120 m,利用测量控制点进行参数校正后定位精度可提高至5 m以内,在地质勘查中熟练运用手持GPS将大大提高野外工作效率。
The positional accuracy of handheld GPS without parameter correction is 80-120 m, using measure control point to corrected parameters, positional accuracy can be increased to 5m. In geological exploration, skilled use handheld GPS will greatly enhance the fi eld work effi ciency.
