Zusammenfassung:	Method of positioning an underground beacon (10) comprising the following steps: - installation on the surface of several surface beacons (20), each surface beacon comprising at least three non-coplanar coils (21A, 21B, 21C) for emitting and/or receiving second radio signals (100); - exchanging first radio signals (200) between said surface beacons (20) so as to transmit data; - displacement of a mobile beacon (10) in an underground cavity (1) said mobile beacon comprising at least three non-coplanar coils (11A, 11B, 11C) for receiving and/or emitting said second radio signals (100); - despatching through the soil of second radio signals (100) between said mobile beacon (10) and said surface beacons (20), - determination of the position of said mobile beacon (10) by means of said second radio signals (100) corresponding to the three second radio signals received by each of the three coils of the receiving beacon from each of the three coils of the emitting beacon. Méthode de positionnement de balise souterraine (10) comprenant les étapes suivantes: -installation à la surface de plusieurs balises en surface (20), chaque balise en surface comportant au moins trois bobines non coplanaires (21A, 21B, 21C) pour émettre et/ou recevoir des deuxièmes signaux radio (100); -échange de premiers signaux radio (200) entre lesdites balises en surface (20) afin de transmettre des données; -déplacement d'une balise mobile(10) dans une cavité souterraine (1)ladite balise mobile comportant au moins trois bobines non coplanaires (11A, 11B, 11C) pour recevoir et/ou émettre lesdits deuxièmes signaux radio (100); -envoi à travers le sol de deuxièmes signaux radio (100) entre ladite balise mobile(10) et lesdites balises en surface(20), -détermination de la position de ladite balise mobile(10) au moyen desdits deuxièmes signaux radio (100)correspondant aux trois deuxièmes signaux radios reçus par chacune des trois bobines de la balise réceptrice à partir de chacune des trois bobines de la balise émettrice.
