<p>The invention described herein concerns a telecommunications and remote sensing system based on the use of a number of satellites placed in elliptical sun-synchronous orbits, inclined with respect to the equatorial plane, having an orbital period of approximately three hours. It belongs to the technical field of artificial satellites and can be advantageously applied to satellite telecommunications including communication through mobile and personal means; radiolocation and radio navigation; simplex or duplex data transmission between small terminals; radio broadcasting; emergency communications. The invention is also applicable to the field of Earth observation, in particular with optical sensors. <IMAGE></p> |
