(.):  The solution of the problem of relative positioning of the alternating magnetic field transmitter and the receiver is to determine the radius vector between the objects under consideration and their mutual orientation. In this paper, determining the mutual spatial location and orientation of two objects in an electromagnetic field problem is set. The relevance is due to the need to improve the accuracy and reliability of the airborne electrical exploration results, especially in the presence of induced interference. The method of electromagnetic field source and receiver relative positioning in the field of two dipoles in a three-dimensional formulation is considered. Two stages are implemented: determining the source-receiver radius vector and their mutual orientation. A technique for calibrating the field source magnetic moments, which is necessary for applying the algorithms, is given. Experimental data of a new airborne electrical exploration system were processed. The results obtained for different positioning algorithms are compared: GNSS solution, two-dimensional electromagnetic positioning in the field of two dipoles, three-dimensional electromagnetic positioning in the field of two dipoles. The possibility of using the obtained solution to improve the quality of the obtained data is analyzed, namely, to control the uncertain nature residual induced interference after the standard compensation method. The study results show that the use of three-dimensional electromagnetic positioning in the two dipoles field allows determining the objects relative position with an accuracy not inferior to the standard GNSS solution, and in the future to deal with the issue of interference, which leads to an improvement in the quality of airborne electrical exploration data.
