ABSTRACT:
A docking target (10) includes three concentric circles (C1, C2, C3) each comprising a plurality of different color light emitting diodes (D1, D2, D3) spaced about the circumference of each circle (C1, C2, C3). During vehicle approach, each circle appears initially as a light spot, then a continuous ring of light and finally a plurality of independent light points at defined distances of the vehicle (14) from the station (12) so that the operator can determine distance of the vehicle (14) to the target (10). The light emitting diodes (D1, D2, D3) on each circle, when visible, provide attitude information of the vehicle (14) with respect to the station (12) by the intensities of the light emitting diodes (D1, D2, D3) and the geometric shape produced thereby so that the operator can adjust the attitude of the vehicle (14) with respect to the station (12).
