Total Electron Content (TEC) reconstruction with GNSS data – a Python 🐍 package with a Rust 🦀 core

PyTECGg is a fast, lightweight Python package that helps reconstruct and calibrate the Total Electron Content (TEC) from GNSS data.

Why calibration matters? Because without it, you don’t actually know the true value of TEC — only how it changes. Uncalibrated TEC is affected by unknown biases from satellites and receivers, as well as other sources of error.

This package:

• is open source: read and access all the code!
• supports all modern GNSS constellations, codes and signals:
  • GPS, Galileo, BeiDou, GLONASS
• supports RINEX V2-3-4
• provides seamless decompression for RINEX files

You can install the package directly from PyPI:

pip install pytecgg

This will also install all required Python dependencies automatically.
