Abstract
The invention concerns a device (1) for locating a target, comprising: —a camera (2) that can be oriented in an orientation in view of the target so that the camera acquires an image of the target, and an orientation in view of a star so that the camera acquires at least one image of the star, —an inertial unit (4) configured to calculate position and orientation data of the camera (2), —a resetting module (6) configured to a apply stellar resetting to the data on the basis of the image of the star, in order to produce reset data, —a location module (8) configured to estimate a position of the target (T) from the image of the target (T) and the reset data, —a communication interface for communicating with an operator station, the camera (2) passing from one orientation to the other in response to the reception, by the interface, of a command sent by the operator station.
