CSSRlib - Toolkit for PPP-RTK/RTK in Python using Compact SSR
CSSRLIB is a open toolkit in Python for high accuracy GNSS positioning. It supports SSR (State-Space Representation) based positioning for PPP (Precise Point Positioning) or PPP-RTK (Realtime Kinematic), while also supporting RTK. The goal of the CSSRlib toolkit is to provide an easy-to-understand open implementation to learn PPP/PPP-RTK positioning provided by satellite-based open PPP/PPP-RTK services such as QZSS CLAS, Galileo HAS, and BeiDou 3 PPP. It also supports ground based open service by IGS. The code is based on RTKlib.
It supports the following open format:
- The observation data and ephemeris in RINEX
- The PPP/PPP-RTK correction data in RTCM SSR, IGS SSR, Compact SSR, ...
- The precise orbit/clock data in SP3 format.

Additional python packages are required as prerequisites and can be installed via the following command
pip install -r requirements.txt
If the installation of cartopy fails, try installing libgeos++-dev first.
sudo apt-get install libgeos++-dev
You can install the official version of CSSRlib using pip
pip install cssrlib
If you want to install the development version from this repository, first clone or download the sources and then run
pip install .
in the root directory, where the setup.cfg file is located.
Run orbit plot sample.
python test_eph.py
Run RTK sample.
python test_rtk.py
Other samples with dataset are also available in a separate repository cssrlib-data including :
- Galileo-HAS PPP (SIS/IDD) processing example
- BDS-PPP processing example
- QZSS MADOCA-PPP processing example
- QZSS CLAS PPP-RTK processing example
- IGS (SP3+BIAS) PPP-AR processing example
- (experimental) PPP via SouthPAN (PVS) processing example
- Binary message parser for Septentrio receiver (Mosaic/PolaRX5)
