Abstract: Obstacle detection and characterisation method, including the steps of: acquiring a first distance measurement obtained from at least one inertial measurement produced by at least one inertial sensor of a mobile terminal, and a second distance measurement obtained from at least one time of flight measurement; evaluating a distance error representative of a difference between the second distance measurement and the first distance measurement; from the distance error, detecting the presence of an obstacle between the mobile terminal and the reference equipment, and determining one or more characteristics of said obstacle.

Abstract: An auto-location method for electronic equipment items provided with a transmitter/receiver of radioelectric signals, includes the steps of: establishing a list of the equipment items with their relative position and the measurements of distances between the equipment items, detecting, using the list, at least one non-measured distance between a first equipment item and a second equipment item, the transmitter/receiver of which has a plurality of available operating modes, changing the operating mode of the transmitter/receiver of the second equipment item and attempting to measure the distance between the first equipment item and the second equipment item, and updating the list with the last distance measured. A system and a program implement this method.

Abstract: Mobile equipment including a geo-localization device arranged to determine a current position for the mobile equipment in a space to be mapped; a communication device arranged to communicate with access points of a local network implemented in the space to be mapped; a control component arranged: to control each access point selectively and in independent manner via the communication device so as to cause said access point to transmit a reference signal; to use the reference signals received by the communication device to evaluate respective qualities for the connections between each of the access points and the mobile equipment in the current position.
