Abstract

The Environmental Mapping and Analysis Program (EnMAP) is a joint German initiative lead by the GeoForschungsZentrum Potsdam, together with the industrial prime ship of Kayser-Threde and the satellite bus responsible OHB-System, under the super-vision of the German Space Agency DLR. The EnMAP satellite will be operational in 2013 with a mission duration of 5 years. 

With its hyperspectral capabilities covering the visible, near- and short-wave infrared wavelengths, EnMAP will provide high quality Earth observation data on a frequent basis. EnMAP provides information based on about 230 spectral bands in the wavelength range from 420 nm to 2450 nm at a ground sampling distance of 30 m x 30 m. 

The EnMAP satellite bus is derived from the proven SAR-Lupe platform of OHB-System. With this platform OHB-System is able to offer a very suitable and cost effective satellite platform for accurate, high resolution Earth observation purposes. The platform provides a scaleable and modular satellite approach, which can form the baseline also for other Earth observation missions in the medium to very high resolution area for optical or microwave applications. 

After a successful execution of Phase B the EnMAP project is right now at the beginning of its realisation in Phase C/D. This paper provides an overview of the project status with a special focus on the EnMAP satellite bus. The paper highlights the bus core elements and their performances and capacities, which enable the fulfilment of the specific EnMAP mission requirements. A special emphasis will be laid upon the modular approach of the satellite bus configuration, as well as on the accurate and agile attitude control concept, and the high rate on-board processing and downlink of the hyperspectral instrument data.
