摘要
本文通过对手持GARMIN etrex GPS接收机定位精度的分析和实践证明,选取适当的校正参数,在一定的观测条件下单点定位误差小于5m,使该接收机为野外米级精度的定位提供了一种经济便捷的手段。
Based on the analysis and the field test of positioning accuracy of mobile GARMIN etrex GPS, this paper suggests an economically convenient and accurate-to-meter way of positioning in open field, which is by means of selecting appropriate revise reference and under certain observation condition to make the unit positioning tolerance less than 5 meters.
