In this article, a remote calibration method of voltage source based on the GPS common-view method is proposed to address the problems of traditional voltage source calibration methods. This method is based on the transfer of non-physical standards and can enable the standard to be placed in the laboratory without having to be transferred to the calibrated site for remote calibration. It can solve the problem of introducing additional errors. By designing the voltage source remote calibration system based on the common-view method, the calibration model is formulated. According to the common-view principle, remote comparison of voltage values between the standard side and the calibrated side can be achieved, and remote calibration of the voltage source can be completed. The calibration results of the remote calibration method and the traditional calibration method at the DC voltage 0~ 1 V calibration point are compared. The results show that the difference between the voltage differences measured by the two methods is within 5. 2×10 -5 V. The uncertainty evaluation process of the two methods at the DC voltage 1 V calibration point is given, and the consistency evaluation of the calibration results of the two methods is carried out by the transfer comparison method. The uncertainty evaluation results show that the extended uncertainty of the remote calibration method at the 1 V calibration point is 9. 182 44×10 -5 V ( k = 2). The calibration results of the remote method are consistent with the traditional results of the remote method.
