Indeed, it is possible to come to house equipment other than those to be housed in the sealed enclosure, around the projecting container 17 and thus optimize the occupation of the volume defined by the container 4 as we will see later .
- This configuration makes it possible to limit the size of the front surface of the immersed part (in water) of the watertight tank 1000 or of the surface unit 5 and thus their drag, when the buoy is in the operational configuration, when a front surface of a submerged portion (in water) of the sealed tank or surface unit comprises a portion of the projecting container and a portion of the tubular side wall 70.
- a front surface of a submerged portion (in water) of the sealed tank or surface unit comprises a portion of the projecting container and a portion of the tubular side wall 70.

- the invention makes it possible to release a space inside the casing 6 and thus to reduce the volume of the casing 6 with respect to a configuration in which the cartridge is entirely housed in the casing 6 of substantially cylindrical shape. It also makes it possible to provide a cartridge 1 1 of volume greater than that of the cartridges arranged in the case without increasing the volume of the case 6 because the size of the cartridges is no longer limited by that of the case. This allows, for the same volume of gas stored in the cartridges, reduce the number of cartridges used without increasing the size of the housing.
- This configuration makes it possible to bring the radio antenna 2 to a higher altitude above sea level and thus to ensure better performance in terms of communication even in rough sea state or to provide sonar emission antennas and / or hydrophones having better acoustic performance and thus a larger mass, without reducing the altitude of the antenna above the water level.
- This configuration also reduces the total volume occupied by the surface unit 5, for the same amount of gas and thus reduce its drag ("drag" in English terminology). Indeed, due to a free volume left between the elements, the volume which must be increased volume of the housing to accommodate a gas cartridge is greater than the volume of the cartridge.
- the limitation of the drag of the surface unit makes it possible to limit the antagonistic drifts of the surface unit and the unit of depth under the effect of counter currents (at the surface and at the level of the depth unit 8 ) which stabilizes the unit of depth 8.
- the gas previously contained in the cartridge, undergoes rapid relaxation which leads to a decrease in its temperature and that of the wall of the cartridge which causes the condensation of water vapor contained air in the housing can thus deteriorate an electronic circuit housed in the housing.
- the reduction in the temperature of the gas can also cause the freezing of this gas, which can then at least partially block a gas evacuation orifice of the cartridge which delays, until a rise in temperature sufficient to ensure the vaporization of the gas. gas, swelling of the inflatable pocket and the arrival of the inflatable pocket on the surface of the water.
- the reduction of the temperature of the gas causes a decrease in its volume which also delays this arrival on its surface. The lower the temperature drop, the longer the gas time to reach its maximum expansion volume, since the gas must return to ambient temperature to reach this maximum expansion volume.
- the proposed configuration accelerates the swelling of the air bag and limit the risk of damage to electrical equipment disposed in the housing.

- a portion of the surface unit 5 is disposed in the tubular volume surrounding the projecting container 17.
- the cable container 14 is secured to the housing 6 so as to be driven by the housing toward the surface of the housing. water when the housing 6 rises to the surface of the water. This embodiment is less advantageous from the point of view of drag.
- the projecting container 17 extends longitudinally parallel to the z axis.
- the protruding container 17 advantageously comprises a cylindrical portion whose axis is parallel to the z axis and is for example coaxial with the housing 6 and / or the cable container 14 (in the storage configuration).
- the cartridge 1 1 of gas is oriented head up.
- the cartridge 1 1 is arranged so that the gas is expelled from the cartridge upwards along a vertical axis connected to the earth when the buoy is dropped and immersed in water.
- the buoy When the buoy is dropped into the water, it takes a natural orientation depending on the position of its center of gravity and its center of hydrostatic thrust.
- the cartridge is advantageously arranged so that the orifice 103 through which the gas will escape is located at the top of the cartridge 1 1 when the buoy and released and immersed when the buoy is in the storage configuration.
- the gas molecules are in the liquid state in the lower part of the cartridge and in the gaseous state at the top of the cartridge, during the release of the gas, when the cartridge is turned head down or is elongated, there are risks of splashing droplets of gas molecules under the effect of the pressure exerted by the gas on the liquid.
- These droplets at very low temperature because of the expansion of the gas
- the so-called "head up" provision of the cartridge makes it possible to limit this risk.
- the cartridge comprises a neck 121, ("neck" in English terminology) delimiting the opening 103 which is closed by the lid 101 in storage configuration.
- the depth unit 8 comprises the cable container 14 and an operational unit 140.
- the operational unit comprises at least one active functional element of the antenna.
- the operational unit is advantageously substantially cylindrical and z-axis in the storage configuration.
