The laser, which has a pulse frequency of 9.6 kHz and a resolution of 1 centimetre (0.39 in), ensures that the pilot can stop in the exact stopping position. The system can be connected with the passenger boarding bridge, apron management system or other airport systems via TCP/IP or

As this system relies on the position of the viewer, it will not give accurate distance information to aircraft which have deviated significantly from the stand centreline.
