Detection of a Point Dipole Signal by a Quantum Gradiometer Under Conditions of Geomagnetic Field Variations

The paper analyzes the effect of geomagnetic variations on the results of measuring the coordinates of a moving point magnetic dipole using signals from a laboratory quantum gradiometer in the form of two M
Z
-type quantum magnetometers with an optical lamp pumping. It is shown that geomagnetic field variations within the laboratory are random and do not depend on the location coordinates of the magnetometers. In addition, the paper discusses the proposed method for determining the distance from the sensitive magnetometer sensor to the magnetic dipole.
