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

摘要

The invention relates to an instrument for of observation images exhibiting a high ground resolution and a high frequency of coverage of the Earth. Such an instrument comprises a spatial images acquisition layer (1) comprising satellites (4), a terrestrial images processing layer (3), comprising images processing devices (5), and a telecommunications layer (2) that is suitable to ensure a transfer of the images from the spatial layer (1) to the terrestrial layer (3), wherein each satellite (4) includes at least one images acquisition device with fixed aim exhibiting a spatial resolution of the order of one metre; each images processing device (5) includes at least one communications line (8) coupling said images processing device (5) and at least one immediately adjacent images processing device, a processing unit that is suitable to process the images received, means for storage of the processed images, and a connection to a digital network.
