Table 5 contains the three-dimensional location of each vehicle sensor. The origin for these measurements was the right front wheel hub. The hub was 370 mm above ground.

The coordinate system used for the sensor location measurements and transducer polarity was as follows:
X-axis - Front to rear of vehicle, longitudinal centerline.
Positive direction toward the front end.Y-axis - Laterally door to door.
Positive direction toward driver door.Z-axis - Floor to roof.
Positive upward out of roof.
