Following the Sentinel-1A launch on 3 April, the Launch and Early Orbit Phase (LEOP) was successfully completed on 6 April. The orbital maneuvers to raise the satellite altitude and reach the reference orbit from the low injection orbit by the Soyuz launcher (-7.8 km) were completed on August 7.
A joint European Commission-ESA press event was organised on 8 May in Brussels on “Sentinel-1A first images and demonstration of applications”, where excellent initial results were presented by external experts. Initial samples of Sentinel-1A preliminary products were made available on-line to all users on 9 May at https://senthub.esa.int. Further Data sets are regularly released via this site for familiarisation purpose and to support preparatory user activities.
The satellite Commissioning Phase is ongoing and is planned to be completed by end September, after which initial operational data provision will start. The observation scenario covering the first three months (October to December) is being prepared and will be made available to the user communities late September. Full and open access to the Sentinel-1 data for all user communities is planned for early January 2015.
