Is accuracy the same throughout the tracker’s motion box?
A. No. If, under static conditions, you move one sensor throughout the motion box (i.e., the volume in which a magnetic tracker meets its accuracy specifications) and measure its position and angular accuracy, you will observe accuracy changes as a function of its location in the motion box. Similarly, if you rigidly fix two sensors near one another in a mechanical assembly and then move and rotate it in the motion box, you will observe the range between the two sensors varies as a function of the assembly’s location in the motion box.
