Getting Started

You need a recent Matlab installation. raPPPid is tested on Windows. Download or clone the raPPPid repository from GitHub, for example, with the following command:

git clone https://github.com/TUW-VieVS/raPPPid

Start Matlab and change the Matlab work folder to the WORK folder of raPPPid, which is a subfolder of the program (/raPPPid/WORK/). Start the Graphical User Interface (GUI) with the function raPPPid.m. You might type the following command into the command window:

raPPPid

Processing Examples

Check the raPPPid wiki: https://vievswiki.geo.tuwien.ac.at/raPPPid/Examples

raPPPid provides functions to download GNSS observation data (e.g., DownloadDaily30sIGS). All other input data is downloaded automatically.

Troubleshooting

Pull the latest raPPPid version from GitHub in case of bugs or errors.

If this does not help, please send a short report, the RINEX file, and settings.mat to raPPPid@geo.tuwien.ac.at
