1. A device capable of determining the direction of a target in a predefined frame of reference and of the type having sighting means (10), means having a sighting member (13), three gyrometers (141, 142,143) arranged along three axes in different planes, means for control (16), means (20) for resetting said sighting means (10) and means (30) for processing signals derived from the sighting means (10), said processing means (30) being capable of determining the direction between the sighting means (10) and the target and of transmitting to imaging means (40) or to external means (50, 60) and also means (16) for controlling the transmission to the imaging means (40) or to external means (50, 60), of representative values of the direction between the sighting means (10) and the target, this device being characterized in that it comprises at least one non gyroscopic sensor (17) arranged on the sighting means (10) and capable to emit a signal for its transmission to the said processing means (30), and in that the processing means are capable of determining a terrestrial frame of reference from the signals derived from the said gyrometers (141, 142,143) and from the said non gyroscopic sensor (17).
