Simplifying speed measurement

The purpose of the lasers in a Berthing Aid System is to measure speed of the approaching ships in order to ensure safe berthing. In ports with large tidal range, problems arise at low tide because the ships are lower than the lasers. The previous models of lasers simply shoot over the side of a small ship at low tide.

Scans up and down until it hits the side of the ship
