PEPS platform

PepsThe PEPS Sentinel products exploitation platform is designed to offer innovative services for accessing Sentinel mission data under the European Copernicus programme to institutional users, scientists and industry. By redistributing data while enabling users to process them on servers close to the source, PEPS is the missing link between the European infrastructure and user access needs at all levels, from local to national. PEPS will thus help achieve Copernicus goals, particularly for implementing and monitoring environmental and security policies. The project should also give impetus to industrial development and the competitiveness of companies further down the Earth observation chain. In response to the needs expressed by users, CNES is defining and implementing the first part of the project alongside its institutional and industrial partners by drawing on the capacity of its own computing centre. This pioneering platform is designed to develop into a European-wide coordinated system involving Cloud businesses.

PEPS has a storage capacity of 7 Petabytes, including 2 on hard disks, sized to be able to store all the global data from Sentinel-1, -2 and -3 up to 2017. The infrastructure can be expanded up to 20 Petabytes. PEPS is scheduled to give on-line access to data as of June 2015, and a later version should also offer users the possibility of processing data on-line. The Theia community will be using PEPS for direct access to the whole data archive and via CNES’s Muscate system to directly access Sentinel-2 data hosted by PEPS in order to make atmospheric corrections (level 2A) and monthly syntheses (level 3A) for areas chosen by the Theia community. Finally, Theia will also have its own storage space within the PEPS infrastructure that will be gradually increased as needed.
