Method and apparatus for locating position in a waterway |
| abstract |
METHOD AND APPARATUS FOR LOCATING POSITION IN A WATERWAY ABSTRACT An electromagnetic energy pulse-echo system combined with a data processing unit and a memory storing the locations of a number of fixed echo reflectors relative to a waterway so that the pulse-echo system operating from a boat can register the echo reflectors and positions in the water-way can be calculated by the data processing unit. |
