The MOMS-2P mission on the Russian Space Station MIR/PRIRODA module

Kurzfassung

MOMS-2P (Modular Optoelectronic Multispectral Scanner) is, as a continuation of MOMS-01, a development for digital mapping of the Earth´s surface from space. The special characteristic of this CCD push-broom camera is the combination of high resolution panchromatic images for 3-dimensional geometric information, with multispectral images for thematic applications. With this concept MOMS-2P is fundamentally different from all existing remote sensing systems and thus pursues new and independent goals. The technical features of the MOMS-2P camera are oriented toward the requirements of the photogrammetric and thematic sciences. The system layout is chiefly specified through such requirements as · three-fold stereo imagery · along-track stereo imagery · high resolution imagery · multispectral imaging · combinations of stereo and multispectral imaging The MOMS-2P camera features, from an orbital altitude of 300 km, a 6 m resolution in the high resolution panchromatic channel and 18 m resolution in the two stereo channels as well as in the four multispectral channels. The band selection was optimized mainly for applications in vegetation investigations. Th MOMS camera was successfully space flight tested on board of the second German Spacelab mission D2 in April 1993. During the 10 days mission approximately 7 mio km2 were covered mainly in the equatorial regions due to the orbit inclination of 28.5°. The survey of the data show excellent results in disciplines like geology, ecology, vegetation investigation and photogrammetry. After a refurbishment the system will be flown for at least 18 months on board of the Russian PRIRODA Module attached to the Space Station MIR in May 1996. So far more than 500 test areas were requested by users from various disciplines such as Agriculture, Ecology, Geology, Photogrammetry etc. In order to maximize the scientific output, a complex mission planning system was installed. The MOMS-2P camera will is commanded through the DLR Space Operations Center in Oberpfaffenhofen, Germany. Data receiving is through stations in Russia as well as the DLR station in Neustrelitz. Additionally in Neustrelitz a ground segment was set up for systematic correction of data as well as archiving and distribution of data.
