Abstract

Abstract: BDS has been completed in 2020 and begins to provide services to the world.Here,we focus on its application in disaster prevention and mitigation.In this study,we present the application of BDS data in crustal deformation research,including monitoring coseismic and interseismic crustal deformation.We also summarize the positioning accuracy of BDS data.Besides,we summarize several key issues,which need to be further solved and expanded,regarding the application of BDS data in crustal deformation.First,in terms of expanding the connotation of GNSS in crustal deformation monitoring,a dual-mode or multi-mode algorithm incorporating both GPS and BeiDou is needed,to improve the positioning accuracy.Second,we need to carry out the application of BDS real-time deformation monitoring in the early identification of geological disasters.Third,we need to develop and publish data processing algorithms and software in order to promote the application of BDS in high-precision crustal deformation monitoring.

Key words: BDS;positioning accuracy;crustal deformation;coseismic deformation;interseismic deformation
