GPS-InSAR Data Integration Method and its Application

Abstract:

The powerful tool of GPS-InSAR integration is drawing more and more attention in deformation monitoring. This paper introduces firstly method of atmospheric corrections and orbit errors to InSAR images using GPS datas. Then, the scheme of GPS-InSAR data integrating is expounded, Finally, Analysis and examples prove that GPS and InSAR technology has highly complementary. On the one hand the GPS provides good approach for resolving sensitivity that the InSAR opposite to atmospheric parameters change and the orbit error correction, on the other hand, we can use GPS technology to raise the InSAR spatial resolution , and are able to monitor surface deformation in millimeter-level precision. Therefore, using GPS-InSAR integrated technology will break through the technical limitations of a single application. They play each of their respective advantages, which greatly improve the resolved capacity in space domain and time domain, so as to provide better services to monitor the surface deformation.
