We describe a laser tracker calibration system developed for frameless coordinate metrology systems. The system employs a laser rail to provide an 'in situ' calibrated length standard that is used to test a tracker in several different configurations. The system is in sewice at NIST and at the Naval Warfare Assessment Station in Now, California. The system description, calibration procedure, and uncertainty budget are presented.
