Prof. Geng Jianghui, the chair of the IGS PPP-AR Working Group, chaired an online meeting of the working group on November 14, 2023. Qiyuan Zhang and Jihang Lin, two group members of PrideLab, joined the meeting and took notes.

The meeting mainly reviewed the recent work progress of the IGS PPP-AR WG, presented the outcomes of the regular clock/bias product combination that the group has been participating in lately, discussed the related technical details, and established the work goals for the following years based on the current development status. Prof. Geng Jianghui had cordial and in-depth discussions with eminent overseas experts such as Prof. Rolf Dach (Vice Chair of the IGS GB), Prof. Oliver Montenbruck (Chair of the Multi-GNSS WG), Prof. Sylvain Loyer (AC Representative), and Prof. Stefan Schaer (Chair of the Bias and Calibration WG), as well as the audience from numerous research institutions around the world. The participants gained a lot from the discussions.

The IGS PPP-AR Working Group was established in 2018 with the aim of enhancing the capability of PPP-AR technology and phase clock/bias products in the field of high-precision GNSS data processing and broadening its application in the IGS community. The group has been devoted to the leading research in this field for many years, and the topics undertaken by the group include providing the product service of all-frequency phase clock/bias from the Wuhan University, demonstrating the interoperability of phase clock/bias products from different ACs, undertaking the tasks of Repro3 and regular combination of IGS clock/bias products, and so on.
