Spacecruft Celestia Galmon
celestia-galmon is a set of scripts to retrieve Galmon GNSS
data and feed it to Celestia for visualization.
The Galmon GNSS Monitoring Project's "goals are to monitor the major Global Navigation Satellite Systems, including GPS, GLONASS, Galileo and BeiDou, but also Space Base Augmentation Systems like WAAS, EGNOS and GAGAN. Galmon is an open source & open data project with a community of over 30 station operators running more than 50 receivers."
Celestia is a "real-time space simulation that lets you experience our universe in three dimensions".

The goal is to have something like the screenshots below, including more Galmon data.
Quick & dirty if you want to use pre-generated file:
sudo mkdir -p /usr/share/celestia/extras-standard/galmon # Use your username for debian sudo chown debian:debian /usr/share/celestia/extras-standard/galmon wget \ -O /usr/share/celestia/extras-standard/galmon/galmon-observers.ssc \ https://spacecruft.org/spacecruft/celestia-galmon/raw/branch/main/extras/galmon/galmon-observers.ssc # Then (re)start Celestia.
If you want to generate your own files:
# Quick & dirty Python setup sudo apt update sudo apt install python3-pip pip install --user --upgrade pip pip install --user -r requirements.txt
Retrieve Galmon observers, output SSC format for Celestia:
./celestia-galmon-observers # Save file for Celestia: ./celestia-galmon-observers > \ /usr/share/celestia/extras-standard/galmon/galmon-observers.ssc
