This  article  addresses  an  analysis  of  the  precision attainable  with  SAOCOM  satellites  for  DInSAR applications. Error model considers orbital, topographic, and atmospheric residual phase terms. It also estimates geometric, doppler, thermal and temporal decorrelation. Results  relevant  for  the  Stripmap  7  Dual  Polarization mode  are  deeply  discussed,  and  summarized  error metrics for all stripmap modes are presented. The study concludes  that  SAOCOM  sensors  will  be  capable  of resolving a good number of real deformation patterns.
