INSTRUMENT FOR ACQUIRING AND BROADCASTING EARTH OBSERVATION IMAGES WITH HIGH SPACE AND TIME RESOLUTION

摘要

The invention relates to an instrument for acquiring and broadcasting observation images having a high ground resolution and a high earth covering frequency. The instrument includes a space layer (1) for acquiring images and including satellites (4), a ground layer (3) for processing images and containing image processing means (5), and a telecommunication layer (2) adapted for transferring the images from the space layer (1) to the ground layer (3), characterised in that: each satellite (4) includes at least one fixed-sight image acquisition device having a space resolution of the order of one meter; each image processing device (5) includes at least one communication line (8) connecting said image processing device (5) and at least one immediately adjacent image processing device, a processing unit for processing the images received, a means for storing the processed images, and a connection to a digital network.
