Prospect on the Integration of GPS and INSAR Data
Xu Caijun · 2003
The necessity and feasibility of GPS and INSAR data integration are analyzed.The error correction in INSAR data by GPS measurements is presented,including orbit error,coregistration error,phase unwrapping error,DEM creation error,temporal decorrelation,and tropospheric delay error.The intetgration of GPS and INSAR data in both time and spatial domains by interpolation and filtering is discussed.
