Abstract
An alternating current (AC) electromagnetic tracker system with increased operational range and an ability to compensate for electromagnetic distortion in the local operating environment. The system uses multiple 'N' sources/transmitters located at known positions in a common reference frame. A sensor receives the generated signal of each of the sources and a processor computes a position and orientation of the sensor from each. The processor further uses the known relative position and orientation between the N sources to compensate for distortion in the operating environment.
