Synthetic Aperture Radar Interferometry (InSAR) has been recognised as a well-suited tool for topographic mapping and ground deformation monitoring applications. However, the spatially and temporally variable tropospheric delay represents a major limitation to InSAR applications. On the other hand, it has become feasible to derive tropospheric corrections from continuous GPS for InSAR due to th...

Global Positioning System (GPS) provides a method for directly obtaining instantaneous position and velocity estimates using satellites-based passive range measurements. GPS is whole day, all-weather, passive, satellite positioning system. Inertial Navigation (INS) navigation aid system that uses computer Measurement Unite (IMU). IMU includes motion sensors rotation to continuously calculate re...

To perform the most precise relative positioning using GPS, it is necessary to resolve the carrier-phase integer cycle ambiguities. This process becomes increasingly difficult as the distance between the mobile and reference GPS receivers increases, due to the decorrelation of the GPS errors with distance, resulting in a practical limit on the distance over which ambiguity resolution can be per...
