PRIDE PPP-AR Short Course 2026 on the EarthScope Platform

On September 16, 2026, Professor Jianghui Geng and Dr. Qiang Wen from the State Key Laboratory of Precise Geodesy, together with Dr. Jiang Guo from the Bureau International des Poids et Mesures (BIPM), were invited to deliver the 2026 PRIDE PPP-AR short course, entitled “Multi-GNSS Precise Point Positioning and PRIDE PPP-AR,” online through the EarthScope Consortium platform. The course attracted experts and researchers from around the world.

EarthScope Consortium is a non-profit university consortium funded by the U.S. National Science Foundation (NSF), with support from the National Aeronautics and Space Administration (NASA) and the U.S. Geological Survey (USGS). Established in 2023 through the merger of the Incorporated Research Institutions for Seismology (IRIS) and the University NAVSTAR Consortium (UNAVCO), EarthScope Consortium is dedicated to advancing transformative approaches to geophysical research and education worldwide and to promoting public understanding of geophysical processes and their impacts.

The course primarily introduced the latest functional and operational updates to the PRIDE PPP-AR software since 2024. These updates include a newly added multipath delay correction based on a hemispherical model and a machine-learning-based validation method for ambiguity fixing reliability. The software also now supports multi-day continuous processing using the WUM0MGXRAP products released by the PRIDE team with continuous day-boundary alignment, which is of significant value for applications such as precise time and frequency transfer.

Since its initial release in 2019, the PRIDE PPP-AR software has received widespread attention from researchers in the field of high-precision GNSS positioning worldwide. In response to feedback and suggestions from users, the PRIDE team has continuously maintained and enhanced the software. To date, the software has been used by researchers in more than 50 countries and regions and has supported the publication of more than 320 high-level research papers, including papers published in Science and Nature. It has also supported the evaluation and validation of high-precision products from the Wuhan Combination Center (WCC) and the Bias & Ambiguity Resolution Committee (BAR) of the International GNSS Service (IGS). In addition, the software has been taught on the EarthScope platform five times, contributing to the development of a growing user and application community.
