The above model represents the volume grid of total measurement space that my equipment is presently designed to measure. The blue cube represents the focus volume for the example glyphs presented on this website. As shown in the model, the position of the tracker (within the blue cube) is the following: x = 3.0, y = 3.0, z = 6.0, h = 0.0, p = 180.0, r = 90.0

x,y,z are measured in feet and h,p,r are measured in arc degrees.
