The article describes modern approaches and provides examples of methods for determining the location of quarry equipment equipped with an automatic motion control system. The object of the study is the process of approaching a quarry dump truck under an excavator bucket at a face for loading overburden. The difficulties arising from the use of satellite navigation are briefly described. A systems analysis of the process of determining the excavator position in the coordinate system of the face is carried out. A coordinate system for an excavator face is proposed, which allows describing the location of the excavator in the form of its displacement relative to the virtual coordinate axes. The diagrams show the technique for determining the excavator position in the face, the place of integration of the coordinate system of the face and the technological road, for which the use of a special device is proposed. Sketches are shown and the main elements of technical devices for determining the coordinates of the excavator in the face without using a satellite navigation system, based on a combination of optical and ultrasonic systems, are described. A simplified description of the method and algorithm for determining the position of an excavator in a face when interacting with automatically controlled dump trucks without the use of satellite navigation equipment is presented.

Keywords:autonomous transport, autonomous vehicle, machine vision, radio direction finding, orientation of moving objects, route, trajectory of movement.
