PrideLab / PRIDE-PPPAR

PRIDE-PPPAR ver. 2.2

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).

PRIDE PPP-AR ver. 2.2 are available for:

1. GPS, GLONASS, Galileo, BDS-2/3 and QZSS capable;
2. High-rate GNSS data processing of up to 50 Hz;
3. Vienna Mapping Function 1/3 (VMF3) for troposphere modeling;
4. Second-order ionospheric correction;
5. High-dynamic mobile platforms applicable for aerial photogrammetry, ship-borne gravimetry, etc;
6. Receiver clock jump mitigation;
7. Multi-day processing;
8. Satellite attitude quaternions;
9. A GUI lite-version provided for very early career researchers;
10. Ambiguity-float PPP using data dating back to 1994 when SA was on;
11. GPS/Galileo/BDS-2/3 PPP-AR in the case of the bias-SINEX format phase biases (ftp://igs.gnsswhu.cn);
12. Adopt both rapid products (RAP) and real-time products (RTS) for more timeliness.

The modifications leading to Version 2.2 include:

1. Batch script name changed from “pride_pppar” to “pdp3”, corresponding command line input parameters also changed;
2. Support multi-day processing;
3. Support for quaternion products;
4. No more DCB products required;
5. The default products after 2020 changed to the multi-GNSS satellite orbit, clock, bias, quaternion and ERP products, which are computed and released by Wuhan University;
6. The table file “leap.sec” needs to be downloaded now, and the “glonass_chn” table file is removed and replaced by the “sat_parameters” table file;
7. GUI version of PRIDE PPP-AR with additional plotting functions;
8. Fix known bugs.

Notes: The multi-GNSS multi-GNSS satellite orbit/clock/bias/quaternion products, which are computed and released by Wuhan University, are required by PRIDE PPP-AR ver. 2.2
