Abstract
The problem of calibration of a vector magnetometer is considered. Technological errors of its production lead to measurement errors that are unacceptable during device operation. A statistical calibration method is proposed based on iterative minimization of the residual of the measurement result and the exact value of the magnetic field induction obtained through the use of a stationary high-precision meter. Experimental results illustrating the effectiveness of the method are presented.
