PRIDE-PPPAR ver. 2.2.6 (last updated on 2023-05-19)

PRIDE PPP-AR ver. 2.2 originates in Dr. Maorong Ge’s efforts on PPP-AR and later developed and improved by Dr. Jianghui Geng's team. It is an open-source software package which is based on many GNSS professionals’ collective work in GNSS Research Center, Wuhan University. We would like to thank them all for their brilliant contributions to this software.

We make this package open source with the goal of benefiting those professionals in their early career, and also advocate the geodetic and geophysical applications of GNSS PPP-AR. Especially, we hope that this package can contribute to high-precision applications in geosciences such as crustal motion and troposphere sounding studies. The entire open-source project is funded by the National Natural Science Foundation of China (No. 42025401) and is under the auspices of IAG SC 4.4 “GNSS Integrity and Quality Control”.

The precise products can be accessed at ftp://igs.gnsswhu.cn/pub/whu/phasebias/. Latest updates for Support, Training courses and FAQ can be found at https://pride.whu.edu.cn. The copyright of this package is protected by GNU General Public License (version 3).
