Environmental Mapping and Analysis Program
The Environmental Mapping and Analysis Program ( EnMAP ) is a German satellite mission with an earth observation satellite .
The aim is the separate recording of various light frequencies, some of which are closely spaced ( hyperspectral ), from the earth's surface. From the analysis of this data information and a. Derive from vegetation, soil and water parameters, which in turn enable conclusions to be drawn about changes in the environment. The primary goal of the mission is to contribute to an understanding of climate-relevant processes.
The start of EnMAP is planned for the end of 2020. The planned operation phase lasts 5 years .
mission
The 980 kg (including 55 kg hydrazine ) satellite records in 242 continuously lined up channels in the spectral range between 420 nm and 2450 nm (blue visible light to short-wave infrared). The spectral signatures are then to be analyzed quantitatively in order to determine geo- and biochemical parameters of the earth's surface and the like. a. can be derived from vegetation, soil and water parameters.
EnMAP records the earth's surface in a sun-synchronous orbit from a height of approx. 650 km with a ground resolution of 30 m × 30 m. The scanning width is 30 km, whereby the satellite can process a strip length of up to 5000 km per day. The possibility of tilting the satellite sideways by up to +/- 30 ° allows comparative observations of the same location within four days.
The German Research Center for Geosciences - Helmholtz-Zentrum Potsdam has the scientific management of the EnMAP mission, the management lies with the space management of the German Aerospace Center (DLR). The sensor is being developed by OHB System AG (formerly Kayser-Threde ). According to a contract between DLR and the company from November 2008, the latter also takes over the system leadership for the mission. OHB System is building the satellite bus that was previously u. a. was used for the SAR-Lupe satellites. The ground segment is planned, built and operated by DLR.
