Abstract
In order to eliminate magnetic heading perturbations coming from the near-field magnetic anomaly, a real-time compensation method is proposed based on magnetic anomaly inversion. Magnetic gradient tensor data arisen near-field ferromagnetic targets was measured by the designed magnetometer array. Then position, magnetic moment, and magnetic scalar values were combined to calculate magnetic vectors of the ferromagnetic targets. Real-time compensation was achiev
