Repeatability Targets Usage and Accuracy Specifications for the Laser Tracker
Repeatability targets can be glued to the object and then measured for the purpose of performing Automated Surveys to check the repeatability or movement of the object. Because they are designed to measure movement from the original location, they do no have a centering tolerance like the Spherically Mounted Retroreflectors (SMR) do.
