EnMAP - Hyperspectral Earth Observation Satellite: Overview Current Status

摘要

The Environmental Mapping and Analysis Program (EnMAP) is a German space borne science mission that aims at characterizing the Earth's environment on a global scale. The single payload of the satellite is the Hyperspectral Imager (HSI). It is capable of measuring the solar radiance reflected from the Earth's surface as a continuous spectrum in the spectral range of420nm to 2450nm, with a spectral sampling of 6.5nm (VNIR) and lOnm (SWIR). The EnMAP swath of 30km is sampled in spatial direction with 30m GSD. In this proceeding, we give an overview of the design and current integration status of the HSI instrument optical unit with additional focus on measured optical and electro-optical performance.
