基于载波相位差分技术的东南极冰川移动监测系统与应用

Application on the Antarctic Glacier Mobile Monitoring System Based on Real Time Kinematic Technique

采用载波相位差分(real time kinematic,RTK)技术在中国南极第32次科学考察中架设了一套基站与一套移动站的一对一监测系统,在东南极开展了对冰川移动的实时监测。获取了2016年2月28日至2017年2月12日的差分数据。通过对数据的处理并结合移动站附近地形,得出测点在监测期间内向西北方向移动了13.9m,且夏季运动速度较冬季快约17.1%.

Glacier movement as an important factor in the response to climate and geophysical changes has been a hot topic in glacier dynamics.Traditional glacier mobile monitoring methods are mostly remote sensing monitoring;In this paper,real time kinematic technology was used for glacier monitoring.The technical principle and system structure were introduced,a monitoring system was established during CHIVARE 32,which consists of a base station and a mobile station in Antarctic ice sheet,and a real-time monitoring of the glacier movement was conducted.The differential data from February 28,2016 to February 12,2017 were obtained.The ice move data were processed and combined with the terrain near the mobile station.It was found that the measuring point moves 13.9 m in the northwest during the monitoring period,and the summer movement speed is about 17.1%faster than that in winter.
