The Environmental Mapping and Analysis Program (EnMAP) is a German space based hyperspectral mission with a targeted launch date in 2012. The single payload hyperspectral instrument uses a dual pushbroom configuration to image the ground at 30m GSD for wavelengths from 420nm to 2450nm with medium spectral resolution. The paper presents the design status of the instrument optical unit which consists of a thermally stabilized optomechanical system comprising two prism based spectrometers with their respective focal planes and a common telescope. Regular in-orbit calibration operations will allow correcting the sensor data to ensure high data consistency throughout the mission. The calibration concept and related on-board facilities will be discussed in conjunction with the sensor characteristics.
