Abstract
A device for permanently maintaining the altitude of a payload the altitude-maintenance energy source of which is practically permanent and extracted from the medium includes at least two gliding bodies connected together by at least one physical link and being, in use, at different altitudes relative to the ground and for which the instantaneous winds have, practically permanently, different characteristics, and further includes a system for controlling the respective attitudes of these two bodies.
