[Launch Date: Estimated June 2014]
Numerous services of high strategic important and economic value are currently being provided based on data from the SPOT or Landsat series of satellites. The
... lifetime of SPOT-5 and Landsat is coming to an end. It is necessary to provide continuity and thus guarantee the availability of data to service providers and users. Enhancement as required by the growing user demand for higher service quality shall be considered. Action has to be started urgently as recognised also by ESA and EC, including the recent communication to European Parliament on Establishing a GMES Capacity by 2008.In addition, activities related to the accommodation of the IR sensor on Sentinel 2 will be added during the second part of the definition study.
