Abstract
The French astronomical satellite D2B is to be launched on September 7975.The spin axis is constantly oriented towatds the sun with an accuracy of ± 30 arc min. The ERC experiment (field recognition) will provide images in three spectral intervals of a region centered at the anti-sun point and having a diameter of 10°. The scanning of this ugion is realized by a combination of the spin motion of the satelli ite and internal electtonic scanning . This experiment includes a catadioptric objective (optimized Kern telescope) with a field of 3° x 6° and an image dissector which analyses the image.
This experiment will achieve a mapping of the Gegenschein and of local regions of the Milky Way with a resolution of 40' x 40' in three spectral bands centered at 2800, 3600 and 4200 Å.
