[IGSMAIL-7759] Phase clock/bias products and open-source PPP-AR software from Wuhan University

[Jianghui Geng]

Dear colleagues,

We have released an open-source software package PRIDE PPP-AR which is
devoted to precise point positioning with ambiguity resolution (PPP-AR). We
hope this package can be useful for high-precision GPS positioning for
geophysical studies and GPS water vapor computation for atmosphere
research. It can output daily/sub-daily static positions, high-rate
epoch-wise positions and zenith troposphere delays/horizontal gradients.
The software comes with a detailed manual describing its structure, usage,
algorithms and relevant copyright issues.

To enable PPP-AR or single station ambiguity resolution, we also generated
phase clock/bias products in the IGS (International GNSS Service)
Bias-SINEX format to achieve the highest precision. At the moment, only the
products from 2006 to 2016 are provided, and we are preparing a routine
processing for the remaining phase clock/bias products. Typically, daily
GPS can achieve better than 2mm, 2mm and 5mm for the east, north and up
components compared to IGS weekly solutions, and epoch-wise displacements
can reach an accuracy of about 1cm, 1cm and 3cm for east, north and up in
terms of RMS.

The entire project is funded by National Science Foundation (41674033,
41861134009) and supported by IAG JWG 4.4.1 “New GNSS Signals for Crustal
Motion Studies". You can download the source code at http://pride.whu.edu.cn
