Abstract
We report on the determination of laser tracker geometrical alignment and angular scale errors using a new geometric error model and repeated measurements of a network of fixed targets which are measured using a laser tracker, mounted in five different locations/orientations. After fitting to the data, we are able to determine geometrical/angular scale errors of the tracker with sufficient accuracy that a previously un-calibrated tracker can easily pass a standard performance verification test, after being error-mapped using our technique. Our technique uses no special equipment, takes under one hour and provides rigorous uncertainty values for the error parameters.
