  "definition": "1. Used in horizontal directional drilling, a highly accurate locating technology that uses gyroscopes, accelerometers, and/or magnetometers to measure the drillhead’s position with respect to the Earth’s magnetic field and/or an induced magnetic field, and to measure the drillhead’s orientation. All of the information is transmitted to the driller through a wire in the drill pipe; it does not require any wireless communication or surface access for a receiver. Compare walkover locator and remote magnetic guidance system.\n\n2.
