手持GPS进行地质矿山测量研究

Handheld GPS for Mine Geological Measurement

现在的地质测量和矿山测量对定位精度的要求比较高,传统的手持GPS难以满足生产要求。首先从理论层面分析目前市场上流行的"亚米级"手持GPS进行地质测量和矿山测量的可能性,接着通过两组实验数据进行分析,对理论上能够达到的精度进行了验证。得出结论:"亚米级"手持GPS在地质和矿山测量中能够达到现代规范要求。最后指出传统手持GPS精度达不到更高的精度的两个原因。一个是受当时软件和技术的原因,另一个是受当时仪器硬件的制约。

The positioning accuracy of thegeological survey and mine survey is relatively high, and the traditional handheld GPS is hard to meet production requirements. Firstly, this paper analyzes the current market popular ＇ submeter＇ handheld GPS for the possibility of geological survey and mine survey from theory, and then the theo- retical accuracy is validated through two groups of experimental data analysis. The conclusion is that ‘ submeter＇ handheld GPS in geology and mine could meet the modem requirements of specification. Finally, this paper points out two reasons for relatively low accuracy of traditional handheld GPS precision. One is subject to the software and technology, another to the instrument hardware restriction.
