Abstract

Strapdown three-axis magnetometer needs calibration before it can be properly employed for navigation purposes. Many scalar calibration methods have been proposed to determine the calibration parameters. However, most calibration approaches seldom describe the influence of sampling distributions on the parameters estimation. As a result, some approaches lack robustness when measurement points are not well distributed. This paper presents the usage of D-optimal design to improve the accuracy and robustness of the solutions for magnetometer calibration problem. The basic idea is to choose the measurement point positions to build a D-optimal design, and then seek optimal solutions of the cost function of the D-optimal design problem by using the particle swarm optimization (PSO) algorithm. Numerical results which show the large improvement in the accuracy and robustness of the solutions are achieved.
