Abstract
Systems, methods, and computer-readable media for calibrating an electromagnetic navigation system are provided. A signal having a first magnitude value and a first phase value is received by way of a receiving antenna. A non-calibrated in-phase component and a non-calibrated quadrature component are computed based on the first magnitude value and the first phase value. A calibrated phase value is computed based on the non-calibrated in-phase component and the non-calibrated quadrature component, and a calibrated in-phase component is computed based on the calibrated phase value, the non-calibrated in-phase component, and the non-calibrated quadrature component. A calibrated quadrature component is computed based on the calibrated phase value, the non-calibrated in-phase component, and the non-calibrated quadrature component, and a calibrated magnitude value is computed based on the calibrated in-phase component. The calibrated phase value and the calibrated magnitude value are stored in a table for use during an electromagnetic navigation procedure.
