GMES Sentinel 1

Within the European earth observation program GMES (Global Monitoring for Environment and Security), OHB-System is responsible for the mission analysis and the optimization of the instrument operations for the first satellite (Sentinel-1). For this purpose, OHB-System is leveraging its skills in mission planning and the optimization of the operations planning for the Sentinel-1 satellites during the current development phase up until the launch and commencement of satellite operations.  

The Sentinel-1 satellites have a C-band radar payload and constitute the follow-up system to the European ERS and Envisat research satellites. The principal contractor for the mission is Rome-based Thalia-Alenia-Space. The purpose of the Sentinel-1 mission is to provide full observation capabilities of global land masses, pack ice regions and main shipping channels at least once every twelve days (one satellite) or once every six days (two satellites). The challenge in optimizing operations is to achieve full coverage of the target regions with only a 25% instrument operation period.
