Erdenezul Danzansan - GNSS geodetic networks development in Mongolia and Its Application in Geodynamic Study - October 29, 2018 • 151 Views
The recent development and establishment of GNSS geodetic networks in Mongolia make it possible to define an increasingly detailed spatial and temporal resolution of the ongoing crustal deformation and to visualize the complex interplay between different orogens in Central Asia. The requirements for establishing permanent stations are based on both off-line and real-time data availability, imposed by global, regional geodetic and local survey actions. The purpose of the study is to evaluate causes of the deformation and stress accumulation of the Mongolian territory by processing digital signals receiving from satellites and linking it with geological structure, and to study possibility of earthquake prediction. All available GPS raw data from continuous sites in the time span 2010-2017 has been analyzed by using the Gamit/Globk software and constructed time series of GNSS stations referenced to a common reference frame that can give fundamental information for both regional and local geodynamic studies and finally produced the tectonic velocity field providing an updated detailed picture of the kinematics (velocity map) and deformation pattern (strain rate map) of the Mongolian area.
