Abstract: Background: In order to explore the sequence of neutrino mass and carry out other advanced scientific researches, Jiangmen underground neutrino observatory is proposed and the project is in the process of site searching. Purpose: This paper mainly introduces the way of position measurement between Jiangmen experimental station and reactor cores of Yangjiang nuclear power plant and Taishan nuclear power plant. Methods: The control network is established and measured by GPS, LGO and the self-developed software is used for data processing and fitting translation. Results: Through the actual measurement, the accuracy of the final coordinate is ±70mm, which meets the tolerance requirement. Conclusion: According to the feedback from the designer, the scheme of the position measurement is reasonable and feasible.
