Abstract: An antenna in a system is provided and includes a first device and at least one second mobile device, where the first device communicates with the second device(s). In an acquisition mode, for each antenna of an antenna system, a first item of communication quality information is obtained, and the antenna the first item of information of which is the highest is selected. In a pursuit mode, if the selected antenna is sectoral, a second item of communication quality information is obtained, and the antenna the second item of information of which is the highest is selected. For each antenna, a third item of communication quality is obtained if the selected antenna is the omnidirectional antenna, and from the third items of information, the antenna the third item of information of which is the highest is selected.

Abstract: Communication system, used in a drone system, based on a communication system of the TDMA type in which the time is divided into a plurality of temporal breakdown hierarchy levels. All the hierarchy levels being suitable for complying with a plurality of constraints related to the drone system comprising a first constraint meaning that each communication between a drone and a station controlling the drone system must be compatible with a conversation audio data transmission, a second constraint meaning that the control station must be capable of controlling a predefined number of drones simultaneously and a third constraint meaning that, the drone system using transmissions by bursts, each burst must be transmitted over a stationary channel.

Abstract: A system for recharging an autonomous aerial vehicle includes a base, a supply boom, a receiving basket, a centering device, and a locking device. The supply boom includes a tip and first recharger. The receiving basket has an inner wall delimiting a cavity that may receive the tip of the supply boom. The receiving basket including a second recharger that is complementary to the first recharger. One of the supply boom and the receiving basket is mounted on the autonomous aerial vehicle while the other is mounted on the base. The centering device centers the tip of the supply boom in the cavity of the receiving basket. The locking device is controlled by a controller and locks the supply boom in the receiving basket.

Abstract: An antenna is selected in a system including a first and at least one second device. The system forms a communication network of TDMA type where each communication occurs in frames. The first device includes plural antennas that each covers a predefined sector near the antennas. The frames are organised in a succession of groups of consecutive frames, each group being organised in a structure associating each frame with a pair formed by an antenna of the first device and of a second device, each possible pair being associated with a different frame in the group according to a position of the frame in the group. For each device including plural antennas: information is obtained representing communication quality between the device's antenna and the first or a second device's antenna, and the antenna is selected having the highest communication quality with an antenna of the first or a second device.
