| Résumé | To improve the efficiency of hydrographic surveying operations on inland and coastal waters it is desirable to employ a parent vessel in the centre, with up to six side vessels running courses parallel to the parent vessel art distances depending on the survey scale. A simple equipment is described which allows the side vessels to maintain their stations with respect to the parent vessel by measuring the difference in the time of arrival between a radio signal and a sound pulse transmitted simultaneously from the parent vessel at regular intervals. The indicating unit also provides a permanent record so that if a side vessel should err from its course, appropriate corrections can be made when the depth soundings are plotted. |
