Abstract:
1. An underwater rock boring apparatus having a differential global positioning system receiver comprising: a boring machine installed at the upper portion of an opening in a barge hull, and having a differential global positioning system (DGPS) receiver at a predetermined location of the body thereof; a differential global positioning system (DGPS) in which the DGPS receiver attached on the boring machine which receives location data from a satellite and a reference station and sends the received data to a control means through a cable; a boring data memory means for storing a boring map that displays both boring target location of an underwater rock and boring location data that are entered through an input means; wherein the input means receives the boring target location data of the underwater rock and integrates the location data of the boring machine with the boring target location data; a display means that respectively displays the location of the boring machine and the boring target location of an underwater rock and monitors the entire procedure; a hull moving means for controlling a location of the barge hull; and a controller for controlling a response to the boring target location data received from the boring data memory means and the boring machine location data received from the DGPS, the operation of the hull moving means and the data received by the input means.
