Abstract
A system is described in which a boring tool is moved through the ground in a region using a drill rig and associated drill string to move the boring tool in a forward direction or in a reverse direction, respectively, through the ground. The boring tool is configured for transmitting a locating signal through the ground. A locating configuration within the system includes a first arrangement for sending a data signal from the boring tool to the drill rig through the drill string. A locator, as part of the system, is configured for tracking an underground position of the boring tool using the locating signal while a second arrangement, at least partly at the drill rig and forming at least a portion of tile locator, transmits the data signal from the drill string to the locator for use by the locator.
