Abstract

Current SPOT-4 technical mission research and development programs concentrate on an increase in geometrical resolution amounting to pixel size of or less than 5 meters; along-track stereo imagery based on two images from the two cameras obtained in a few seconds; and continuity of the SPOT service. Modifications to be made to the camera design include the optical combination for a high quality image to 1.6 micron and development of large band visible and MIR optical coating; development of a 3000-point detector for the MIR band; complete rearrangement of the focal plane; complete redesign of the video electronics to eliminate interference and correct obscurity signals; and installation of active temperature control on the MIR channel.
