3-Dimensional Position Determination using Ultrasonics (Nixen)
|
A 3-D position measurement system was developed using ultrasonics to provide
a measure of the position of the bucket-wheel dredger discharge boom
relative to the conveyor hopper:
|
operates in dust and fog
|
|
10m volume coverage
|
|
0.1m precision over all environments
|
|
uses GPS-like algorithms
