Tool for procurement and distribution of Earth observation images of high spatial and temporal resolution.

摘要

Instrument for acquisition and distribution of observation images of the Earth of mean circumference C comprising: - a constellation of satellites (4) which is called layer (1) spatial image acquisition, each satellite (4) a scan width F and a low orbit so that it can describe a number ORB (ORB 1) of orbits in one day, and each satellite equipped with at least one optical imaging device being. - a plurality of devices (5) terrestrial treatment and distribution of images received by the terrestrial name layer (3) for processing and distribution of images, - a network of data transmission is called a layer (2) telecommunications and is adapted to ensure a transfer of the images taken by the spatial layer (1) image acquisition to said terrestrial layer for processing and distribution of images, said layer (2) of telecommunications comprising: - for each satellite (4 ), at least one transmission module adapted to send, after each acquisition of image by an optical device imaging of this satellite, the image (9) acquired towards said layer (3) Ground treatment and distribution image, - for each terrestrial device (5) for processing and distribution of images, at least one module (12) adapted to receive images (9) proc edentes of said layer (1) spatial image acquisition; characterized in that: - said layer (1) spatial image acquisition comprises, for each satellite (4), at least one optical device imaging fixed viewer having high spatial resolution, - said layer ( 3) Ground treatment and distribution of images comprises, for each device (5) for processing and distribution of images, at least one line (8) connecting this to this land device (5) treatment and distribution images and at least one earth processing device and image distribution immediately adjacent, so as to enable overlaps of the images received by the terrestrial device (5) for processing and distribution of images with images received by this (these) device ( s) land (s) of treatment and distribution of images immediately adjacent (s), - each device (5) treatment and distribution images comprising: - a unit (11) of adapted to process the images (9) received by the module (12) for receiving the terrestrial device (5) for processing and distribution of images, - means (13) for memorizing of treated by the unit (11) of images - a connection (14) to a digital network (15) in order to put said memorized images available to users connected to the network (15) number.
