一种使用GPS、罗盘和激光测距仪测定南极冰川运动的方法

南极冰川运动,是研究南极冰雪物质平衡、环境变化等的重要因素,对其的监测具有重大意义。本文提出了一种配合使用GPS、罗盘和激光测距仪实现测定冰川运动的方法。该方法在完成标定和在冰川上放置标志杆后,无需靠近冰川,只根据远处工作站的GPS、罗盘读数和激光测距仪的测量值就能给出标志杆的GPS数值,从而监测冰川的运动。

The movement of the glacier in Antarctic is an important factor in the research of Antarctic ice and snow mass balance and the Antarctic environment change,so the measurement of ice velocity of the Antarctic glacier is significant.This paper presents a method of using GPS,compass,and laser scanner to measure the glacier movement in Antarctic.After calibration and setting the marker pole on the glacier,our method can give the GPS values of the pole by analyzing the outputs of GPS,compass and laser scanner at...
