A system for space-based imaging in three dimensions includes at least two satellites in a geocentric orbit in a same orbital plane, a satellite being equipped with equipment for optical imaging in two dimensions and a system for transmitting to the ground images in two dimensions; at least one data receiving station on the ground, connected to a communications network; at least one center for processing the images received in two dimensions from the satellites in order to create resulting images in three dimensions and to broadcast the resulting images in three dimensions, the processing center being connected to the communications network; and, a system for controlling the satellites such that a geographical area of the Earth of which images are to be taken is seen under an angle of incidence with respect to a nadir greater than a minimum threshold and/or less than a maximum threshold.
