The invention concerns a device () for locating a target, comprising: &#x2014;a camera () 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, &#x2014;an inertial unit () configured to calculate position and orientation data of the camera (), &#x2014;a resetting module () configured to a apply stellar resetting to the data on the basis of the image of the star, in order to produce reset data, &#x2014;a location module () configured to estimate a position of the target (T) from the image of the target (T) and the reset data, &#x2014;a communication interface for communicating with an operator station, the camera () passing from one orientation to the other in response to the reception, by the interface, of a command sent by the operator station.

A method for processing high-frequency movements in an optronic system including an image sensor functioning with a first acquisition frequency, each image obtained by the image sensor representing a scene, the method includes a step of obtaining signal values representing a movement of the scene from a high-frequency movement sensor functioning with a second acquisition frequency higher than the first acquisition frequency, a step of determining values representing a movement of an image in the course of acquisition by the image sensor from values of the signals representing the movement of the scene, and a step of transmitting the values representing the movement of the image in the course of acquisition by the image sensor to a movement compensation device so that the movement compensation device can compensate for the movement of the image in the course of acquisition by the image sensor.
