摘要
Abstract
Tri-axial magnetometers are widely used in measurement of static magnetic fields. The diversionary error caused by non-orthogonality and different sensitivities among three axes is sure to reduce the accuracy of tri-axial magnetometers. There-fore , the calibration of the total measuring error is needed for accurately measuring the modulus value. The mathematic relation between the measured value and ideal value of the tri-axial magnetometer is analyzed, and the mathematic model for error correc-tion is deduced. The objective function with weight factors is proposed. The error parameters are calculated with PSO algorithm. Practical measurement data was used to verify the correctness and effectiveness of the method.关键词
