Determining the mechanical center of the beam position monitor(BPM) has been a difficulty for BPM calibration. To solve this problem, a method of positioning the BPM mechanical center based on laser ranging is proposed. This method uses high-precision antenna support as the core locating datum, and high-precision laser ranging sensors(LRSs) as the detection tool. By detecting the distances from the LRSs to the antenna support and the distances from the LRSs to the BPM, the mechanical center of the BPM can be indirectly determined. The theoretical system error of this method is within 20¿m, and the experimental results show that the measurement repeatability is less than 40¿m, This method has low cost and fast speed, which can be used for large-scale calibration.
