    Abstract

    This paper covers new concepts in the field of Earth Observation systems for Germany and Europe ranging from science and research towards operational missions. Very high resolution multi-spectral, hyperspectral, as well as very high resolution SAR mission concepts are presented including the following projects:

    • The SAR-Lupe constellation will generate very high resolution SAR images of <1m for military reconnaissance purposes with fast response time, currently in-orbit deployment. The constellation provides inter-satellite-links and will be operated for 10 years.
    • EnMap - featuring innovative hyperspectral sensor systems for the detailed and global analysis of eco-system parameters. The sensor provides more than 200 spectral channels from VNIR to SWIR with spatial resolution of 30m.
    • Very high resolution Optical mission below 1m resolution are proposed for reconnaissance and dual-use applications of governmental customer. Here next generation system core elements are presented.
    • Very high resolution SAR and Optical constellations of 1m resolution are currently investigated for emergency response and disaster management services as investigated as GMES core services and GMES service elements. The main user require is a fast system response-time. Constellations in combination with current very high resolution systems will that will be significantly improved
    • Ocean-Colour from GEO shall be a sustainable source for intra-daily data relevant for coastal zone services for environment monitoring, fisheries management and coastal water pollution. The system will provide 14 spectral channels in VNIR with 300m spatial resolution. This will be complementary to the current GMES Sentinel-3 mission.

    Also the fast delivery of large data volumes is an issue for very high resolution systems. Here GEO data relay satellite are currently investigated as a possible solution for the growing demand of data traffic from EO satellite to ground stations. The performance and the main features of the missions and satellites will be described.
