Electromagnetic trackers have direct applications in many different fields including, but not limited to, three-dimensional (3-D) measurement and analysis of human movement for bio-mechanical studies, 3-D animation, military applications such as tracking the line of sight in aircrait helmets, and medical applications such as tracking medical instruments inserted into the body. This project examines the algorithm used to calculate the distance and orientation of the sensor with respect to the source. In the original algorithm, the source is assumed to be a point source, thereby eliminating higher-order terms from the magnetic field calculation. The effect of these higher-order terms on the-accuracy of the calculation of the distance and orientation was examined with the result that they did not have any significant effect on the overall calculation.
