Abstract: Electronic system for the remote control (3) of drones (2), designed to detect a risk of passing authorized flight zone limits as a function of authorized flight zone limit definition data of the authorized flight limit(s) and the geographical location of the drone or a remote control command received and for determining, as a function of the control command and extrapolation over time of control according to this command, a limit-passing status, and triggering an alarm as a function of the determination; or determining another remote control command intended for the drone to prevent the passing of a flight zone limit; or blocking the transmission to the drone of the remote control command received in order to prevent the drone passing the flight zone limit.

Abstract: A communication network, communication installation within an aircraft and aircraft including such a communication installation are disclosed. In one aspect, the network is adapted for interconnecting pieces of electronic equipment and includes a set of at least three network switches, each being connected to all of the other network switches of the set. Each network switch includes several communication ports. The network further includes a plurality of datalinks, each being configured to connect one network switch bidirectionally to another network switch of the set, via the corresponding communication ports. At least two separate network switches are configured to be connected directly to a same piece of electronic equipment.

Abstract: An aircraft pilot assistance system is disclosed. In one aspect, the system includes at least one primary chain and at least one secondary chain. Each chain can include a plurality of interconnected electronic modules, the primary and secondary chains differing from one another by at least one electronic module. Each chain can be configured at least to retrieve pilot assistance information and to implement at least one of the following avionics functions: automatic piloting, flight plan management and trajectory development, and alert generation in case of malfunction of the aircraft or in case of detection of at least one risk on the trajectory. The primary chain can be configured to operate according to a nominal pilot assistance information retrieval mode, and the secondary chain can be configured to operate according to a downgraded mode in which the information from the nominal mode is partially retrieved.

Abstract: This method makes it possible to validate an update file of at least one set of computer data of a piece of avionics equipment of an aircraft. The processing method is implemented within a processing system comprising a mobile terminal independent of the aircraft, an update unit integrated into the aircraft, and a database separate from the aircraft and the mobile terminal, and comprises obtaining a computed message digest, the computed message digest resulting from the application, by the update unit, of a cryptographic hash function to the update file, obtaining a reference message digest, the reference message digest being acquired by the mobile terminal by secure access to a database comprising the reference message digest, and processing the update file based on a comparison of the computed message digest with the reference message digest.

Abstract: An electromagnetic position and orientation detector. A determination is made by a calculator of the position and the orientation of a mobile sensor as a function of the coupling coefficients measured between each of the coils of the sensor and each of the coils of a transmitter. These measurements are tainted with errors due to the imperfections in gain of the various elements of the transmission and reception channels. To eliminate these errors, a stationary sensor is used whose coupling coefficients with the coils of the transmitter are measured to serve as a reference to correct the coupling coefficients between the coils of the transmitter and of the mobile sensor.
