An underwater positioning system (501) provides position information for a rover that is moveable underwater in a reference frame. The system includes a light source (530), a beacon (504), and scaling element (512, 528). The light source is moveable together with the rover between different positions with respect to the reference frame. The beacon includes an underwater imaging device (510) and is deployable in the water at a fixed position with respect to the reference frame. The underwater imaging device observes the light source at the different positions and determines direction data representing a direction or change in direction of the light source with respect to the imaging device. The scaling element provides scaling data representative of a distance between the imaging device and the light source.
