Abstract
The device for determining the relative attitude and range of a chaser vehicle and of a target vehicle comprises, on the chaser, a camera for forming the image of a field of view of determined angular extent and, on the target, a set of several markers. The spacing between the markers is such that they are at least partially outside the angular field of view of the camera carried by the chaser when the range between the chaser and the target is less than a determined value, and the target (11) carries reflector means (16) which remain entirely within the field of view, even at ranges less than said value, and which provide images of the markers (14) in the field of the camera.
