      If you are talking about sub-pixel positioning, estimated from the cardinal sine peak, this is optional (it’s the third button in the “amplitude processing” frame, “site processing” window). By default, no sub-pixel position is used, only the pixel integer coordinates.
      But for geocoding you need also the height. By default, external DEM height is used. However, if you run the InSAR time series processing and if you improve the height by estimating the remaining component (in addition to the ext DEM), the corrected height is used (ext DEM plus residual).
