Abstract
A method of acquiring and repatriating satellite data representative of a zone in space, termed the target zone, and an instrument for acquiring and repatriating satellite data including a plurality of satellites (1, 100), a plurality of terrestrial receiving stations (50, 51, 52, 53, 54), the instrument includes, for each item of data received by a receiving station (50, 51, 52, 53, 54), termed the receiving station, originating from the space layer: elements for determining a receiving station (50, 51, 52, 53, 54) intended for storing this item of data, termed the receiving station competent in respect of this item of data, and a terrestrial digital network for routing this item of data from the station receiving this item of data to the receiving station competent in respect of this item of data.

17. Process for acquisition and downloading of satellite data pertaining to a zone of space, named the target zone, in which:
-
data are acquired by a constellation of satellites, named the spatial layer, each satellite being equipped with at least one device for acquisition of data, the data are transmitted to a plurality of receiving stations distributed over the surface of the globe, named the terrestrial layer, each receiving station including at least one receiving module for receiving data and storage means for storage of received data, wherein, for each datum received by a receiving station, named the receiver station, and emanating from said spatial layer; a receiving station intended to store this datum, named the competent receiving station, is determined by determination means, this datum is stored by said storage means of said receiver station of this datum if this receiver station is the competent receiving station for this datum, this datum is routed, by means of a terrestrial digital network interlinking the receiving stations with each other, from said receiver station to said competent receiving station for this datum if said receiver station of this datum is not said competent receiving station for this datum. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 34)

25. Instrument for acquisition and downloading of satellite data that are representative of a zone of space, named the target zone, comprising:
-
a plurality of satellites named the spatial layer for acquisition of data, each satellite being equipped with at least one device for acquisition of data pertaining to at least one portion of said target zone, and with means for transmission of the acquired data to the ground, a plurality of terrestrial receiving stations, named the terrestrial layer, each receiving station including a module for receiving data stemming from said spatial layer and means for storage of data stemming from said spatial layer, wherein said instrument includes; for each datum received by a receiving station, named the receiver station, and emanating from said spatial layer, means for determination of a receiving station intended to store this datum, named the competent receiving station for this datum, a terrestrial digital network interlinking the receiving stations with each other, so that a datum received by a receiver station that is not said competent receiving station for this datum can be routed by means of this terrestrial digital network to the competent receiving station for this datum. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33)
