FIELD: physics.
SUBSTANCE: reference geophysical points fitted with gravimeters and magnetometres are installed on an a water body. Reference values of gravitational acceleration and geomagnetic field induction vector are determined. Gravimetric and magnetic survey is carried out on loop routes with closing on reference points. The desired values of gravitational acceleration and the magnitude of the induction vector at each measurement point are determined as the sum of increments of the measured parameter to the previous, starting with the reference geophysical point.
EFFECT: wide range of measured parameters.
