CLSs Jean-Yves Le Bras said: "In the framework of MARISS, CLS acquired ERS-2 images through the Mas Palamas station in September 2007 to perform trials in the West Mediterranean Sea. The trials have shown that near real time capability and good geolocation performance can be obtained from ERS-2, allowing for potential in an operational context. In particular coupling with other missions could be valuable, for example provision of additional information in the co-located part of an Envisat Wide Swath image."
Satellite synergy within 30 minutes
Key users have also expressed considerable interest in the 30-minute time difference between the overpasses of ERS-2 and Envisat. The minimal time lag allows data to be retrieved and used from ERS-2 when Envisat is being used in a different mode. For example, in the case of oil slick monitoring, Envisat can obtain acquisitions in Wide Swath Mode while ERS-2 provides a more detailed view. This unique capacity is approaching update times of conventional systems, such as the AIS, and is currently unique for satellite surveillance systems.
ERS-2 sets stage for GMES
ERS-2 with its well-defined products and services has an important role to play in the preparation for GMES, building on the established customer base through the generation of policy-relevant services. Until the launch of GMES-dedicated missions, such as Sentinel, the retention of ERS-2 will provide the necessary additional capacity to maintain the uninterrupted data flow that is critical to the programme.
GMES responds to Europes needs for geo-spatial information services by bringing together the capacity of Europe to collect and manage data and information on the environment and civil security, for the benefit of European citizens. As the main partner to the European Commission (EC) in GMES, ESA is
