The Galmon GNSS Monitoring Project - Bert Hubert's writings
a day ago
- The Galmon project monitors major GNSS (GPS, GLONASS, Galileo, BeiDou) and SBAS (WAAS, EGNOS, GAGAN) systems.
- It is an open source and open data initiative with over 30 station operators running more than 50 receivers.
- The goal is to help all GNSS users, research institutes, vendors, and operators, without affiliation to any supplier.
- The project emphasizes transparency by recording every satellite message rather than just receiver positioning accuracy.
- Currently provides near 24/7 coverage of Galileo and GPS; needs additional receivers for GLONASS, BeiDou, and South American regions.
- Offers a website, Twitter feeds (@GalileoSats, @GNSS_Changes), raw data access, a graphing server, and an IRC channel.
- To join, you need a UNIX computer (e.g., Raspberry Pi) with a U-blox 8 or 9 chipset; installation instructions are on GitHub.
- Data transmission to the project requires contacting the team for a station number and server address.
