Abstract: Task of the invention is an autonomous stratospheric unmanned airship (10) with the operating altitude from 5 to 22 km and with the operational cycle measured in months. Spheroid rigid frame of constant volume is done as a geodesic frame (11) formed by a multitude of struts (28), with an outer envelope (12) enclosing the frame (11) defining the eigenfrequency spectrum of the airship (10) in the frequency range above 20 Hz, with the vibrational amplitudes between 0,1 and 1 cm. Independently controllable electrical propulsion units (14) are attached to the frame (11) in the horizontal plane passing through the center of mass, and can change the direction and the value of the thrust vector. Buoyancy is controlled with a system integrated inside the geodesic frame (11) consisting of pressurized tanks (23) containing buoyant fluid, valves (24) for the release of the buoyant fluid through the buoyant fluid conduit (26) into the buoyant gas cell (38) which by expansion fills the geodesic frame (11); and valves (18) placed at the subsystem support platform (17) enabling ambient atmosphere to fill the internal volume of the frame (11) not occupied by the buoyant gas cell (38). Additionally, inside the frame (11) is a power system comprised of batteries (32) and photovoltaic cells (13) placed at the upper part of the envelope (12). Besides the communication system (36, 37) and antennas (19, 20) airship has a control unit (32) and a specialized scientific equipment for various purposes placed at the platform (17) in a form of payload (34).
