Several contributing factors were analyzed to determine a combined expanded uncertainty for the artifact during an
interim test: alignment and performance of the tracker when calibrating the reference length, repeatability of seating a
retroreflector in a target nest, gravity loading of the artifact in varying orientations, target reflectors used in the length
measurement tests, and temperature effects. This uncertainty is based on validity conditions appropriate to field
use:
• The artifact has soaked in the environment and will not vary in temperature more than ±1°C from the
temperature at time of calibration.
• The artifact is calibrated in the horizontal orientation only.
• The test is to be conducted within 1 hour.
