Abstract
An instrument for of observation images exhibits a high ground resolution and a high frequency of coverage of the Earth. Such an instrument includes a spatial images acquisition layer (1) including satellites (4), a terrestrial images processing layer (3), including 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 the images processing device (5) and at least one immediately adjacent images processing device, a processing unit that is suitable to process the images received, element for storage of the processed images, and a connection to a digital network.

15. Instrument for acquisition and distribution of observation images of the Earth of mean circumference C comprising:
-
a constellation of satellites, called the spatial images acquisition layer, each satellite exhibiting a swath F and a low orbit so that it can describe a number ORB (ORB>
1) of orbits in one day, and being equipped with at least one optical images acquisition device,a plurality of terrestrial images processing and distribution devices, called the terrestrial images processing and distribution layer, a data-transmission network, called the telecommunications layer, that is suitable to ensure a transfer of the images captured by said spatial images acquisition layer to said terrestrial images processing and distribution layer, said telecommunications layer comprising; for each satellite, at least one sending module that is suitable to send, after each acquisition of images by said at least one optical images acquisition device of pertaining to said satellite, the acquired image to said terrestrial images processing and distribution layer, for each terrestrial images processing and distribution device, at least one receiving module that is suitable to receive images resulting from said spatial images acquisition layer, wherein; said spatial images acquisition layer comprises, for each satellite, at least one optical images acquisition device having a fixed aiming and exhibiting a high spatial resolution, said terrestrial images processing and distribution layer includes, for each terrestrial images processing and distribution device, at least one communications line coupling said terrestrial images processing and distribution device and at least one immediately adjacent terrestrial images processing and distribution device so as to enable overlaps of the images received by said terrestrial images processing and distribution device with images received by said at least one immediately adjacent terrestrial images processing and distribution device(s), each terrestrial images processing and distribution device comprises; a processing unit that is suitable to process the images received by said receiving module of said terrestrial images processing and distribution device for, memory means receiving and storing said images processed by said processing unit a connection to a digital network allowing to place said stored images at the disposal of users coupled to said digital network. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
