A method for assisting with the navigation of a fleet of vehicles including a main vehicle and a secondary vehicle that is mobile in relation to the main vehicle, the method including receiving relative movement data, acquired by one or more sensors, between the main vehicle and the secondary vehicle, estimating a navigation status of the fleet of vehicles by an invariant Kalman filter using the received data as observations, the navigation status including first variables representing a first rigid transformation linking a location mark associated with the main vehicle to a reference point, and second variables representing a second rigid transformation linking a location mark associated with the main vehicle to a location mark associated with the secondary vehicle, the invariant Kalman filter using, as an internal composition law, a law including a term-by term composition of the first rigid transformation and the second rigid transformation.
A method for assisting the navigation of a first carrier stationary relative to a second carrier itself movable in a reference frame, the method comprising the following steps implemented by the first carrier:
A device for assisting the navigation of a first carrier stationary relative to a second carrier itself movable in a reference frame, the device comprising:
A device for assisting the navigation of a first carrier stationary relative to a second carrier itself movable in a reference frame, the device comprising:
