Abstract

An apparatus and method for compensating a coordinate measurement machine is provided, which may be a laser-based coordinate measurement machine, laser tracker, or other coordinate measurement device. In one exemplary method, such compensation comprises self-compensation of payload parameters by means of embedded tracker targets. In another exemplary embodiment, such compensation comprises self-compensation of payload, azimuth-post, axis, or R0 parameters by means of embedded temperature sensors.
