Total Electron Content (TEC) reconstruction with GNSS data – a Python 🐍 package with a Rust 🦀 core.
What is PyTECGg?¶
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.
Main features¶
This package is designed for researchers and engineers who need speed and reliability.
- Blazing fast: powered by a Rust core and Polars, it is much faster than existing pure-Python implementations when parsing large datasets.
- Open source: read, access, and contribute to all the code.
- Modern GNSS support: compatible with GPS, Galileo, BeiDou, GLONASS.
- RINEX ready: supports versions 2, 3, and 4.
- Seamless decompression: built-in support for Hatanaka-compressed files — no need to decompress your data manually.
