Sentinel-1A, the first component of the Copernicus Space Segment developed by the European Space Agency, was launched on 3 April 2014. It was commissioned in orbit during the following months leading to an In-Orbit Commissioning Review in September 2014. The identical Sentinel-1B has been recently launched on 25 April 2016, two years after Sentinel-1A to complete the Copernicus Sentinel-1 constellation. After its launch, the LEOP Phase was successfully completed in less than three days when all subsystems were checked. The SAR instrument was switched on, checked up and acquired the first images that were downloaded and processed by the operational Ground Segment. At present, the four-month Commissioning Phase is on-going; it includes the in-orbit Calibration and Characterisation and the verification of the satellite, in order to deliver a full functional and well performing satellite to the mission operations mid September. This paper present the LEOP results and the planned Commissioning activities.
