Abstract：A kind of external physical standard for laser tracker base station calibration was designed， which was caled BSC. Firstly，the principle of BSC of laser tracker was introduced.Then a highprecision CMM was used to measure the repeated positioning accuracy of the BSC，which verified the characteristics of high-precision repeated positioning，verified the feasibility of the calibration principle of the base stations，and might realize the accurate positioning of the target mirror in space.Finally，the BSC was introduced into the CNC machine tool positioning error measurement experiments，and the measurement results were compared with that of the laser interferometer.The research finds that the two measurement principles of the error value change trends are basically the same，the maximum deviation of X axis positioning error measurement is as 1.8μm ，the maximum deviation of Y axis positioning error measurement is as . The results show that the calibration principle of the BSC is feasible，the accuracy meets the calibration requirements of the laser trackers，and the measurement results are in good agreement with the existing mature equipment.This method puts forward a new idea and method for the calibration of the laser tracker base stations.
