Method and system for acquiring and repatriating satellite data
First Claim
1. A process for acquisition and downloading of satellite observation image data representing a zone of space (“
- the target zone”
), comprising;
acquiring data by a constellation of satellites (“
the spatial layer”
), each satellite being equipped with at least one device for acquisition of data; and
transmitting the data to a plurality of receiving stations distributed over the surface of the Earth (“
the terrestrial layer”
), each receiving station including at least one receiving module for receiving satellite observation image data and storage means for storage of received satellite observation image data,wherein, for each satellite observation image datum received by a receiving station (“
the receiver station”
) and emanating from the spatial layer;
a receiving station, that stores the satellite observation image datum (“
the competent receiving station”
), is determined by determination means,said satellite observation image datum is stored by said storage means of the receiver station of said satellite observation image datum if the receiver station is the competent receiving station for said satellite observation image datum, andsaid satellite observation image datum is routed, by means of a terrestrial digital network interlinking the receiving stations with each other, from the receiver station to the competent receiving station for said satellite observation image datum if the receiver station of said satellite observation image datum is not the competent receiving station for said satellite observation image datum.

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.
