Abstract The method on proving data consistency of each laser tracker through the share transfer standard which is one of China’s general quantity value transfer method is put forward . The difference of the result that each laser tracker gets when they calibrate the same reference length is investigated, as well as the infl uences engendered by the different spot environment on the comparison result. The method of indirect traceability of laser tracker through group technology is discussed. New pathways toward comparing traceability interlink are researched.
