Professor Jianghui Geng Visits BIPM at Invitation

Professor Jianghui Geng paid a visit to the headquarters of the International Bureau of Weights and Measures (BIPM) in Sèvres, France, on May 11, 2026. The invitation was extended by Professor Giulio Tagliaferro and Professor Patrizia Tavella of the BIPM. During the visit, both sides delivered academic presentations entitled "Multi-Constellation IPPP Link for UTC" and "The IGS Activities at Wuhan." The discussions focused on cutting-edge topics such as GNSS precision products for enhanced global time and frequency transfer. The talks proved to be in-depth and productive, leading to a consensus on future collaboration. The visit lays a solid foundation for joint innovation between the two parties in the fields of time and frequency metrology, as well as GNSS applications.
