Abstract
Laser tracker testing normally means a standardised set of measurements against calibrated artefacts. This talk proposes something different: determine a tracker's alignment errors from a network measurement, fitting the instrument's error model to the redundancy in the network itself. Ben Hughes sets out the errors a tracker has, the model that describes them, how trackers are conventionally tested, NPL's proposed method and the results it gave.
