FIELD: physics; geophysics.
SUBSTANCE: invention relates to geophysics and can be used to determine specific conductivity of soil, rocks and other bodies above and below the surface of the earth. Invention discloses a geophysical survey method and a system which include measuring along multiple axes at multiple locations within a survey area a low frequency magnetic field component resulting from naturally occurring electromagnetic sources using a first sensor system; measuring along multiple axes the low frequency magnetic field component resulting from naturally occurring electromagnetic sources using a second sensor system; and receiving information about the magnetic field component measured by the first sensor system and the second sensor system; and computing parameters from the received information which are independent of rotation of the first sensor system or the second sensor system about any axis thereof.
EFFECT: high accuracy of exploration data.
