The TerraSAR-X2 Mission is intended to insure the TerraSAR-X service continuity from 2016 onwards and to provide new very high resolution products with improved performance parameters to the user community. The TerraSAR-X2 Mission will benefit from an advanced SAR sensor technology allowing a spatial resolution down to 0.25 meter depending on selected and allowable chirp bandwidth in the future. Besides the advanced Very High Resolution Modes the TerraSAR-X2 satellite will provide heritage modes that allow direct continuity of TerraSAR-X data and improved wide swath modes to support large area applications. In addition the TerraSAR-X2 Mission will feature full polarimetry and improved near real time capabilities. The TerraSAR-X2 Mission and potential extensions will be subject to a partnership model, “WorldSAR”, in which partners can participate through co-investment, subscription, and up to ownership of additional satellites operated in constellation. Service continuity through TerraSAR-X2 is intended to be ensured from 2016 until 2025, taking benefit of a 9.5 years satellite lifetime.
