Galileo OSNMA (Open Service Navigation Message Authentication)

A python implementation of the Galileo OSNMA protocol.

PIC2BIM connects building information to authenticated and accurate geotagged photos using Galileo satellites.

A cross-platform console tool that parses mixed GNSS data streams containing **SkyTraq Binary**, **NMEA 0183** (including SkyTraq proprietary `$PSTI`), and **RTCM 3.3** messages — from a serial port or a captured log file.

Breaking state-level MitM and cryptographic isolation by delivering Certificate Transparency logs via OSNMA-authenticated satellite signals (GNSS/LEO).

Self-contained C++20 library for decoding Galileo E1-B I/NAV and authenticating navigation data with OSNMA.

A security-first, no_std-capable GNSS framework for Rust, built from scratch for raw SDR reception, satellite signal processing, navigation messages, positioning, timing, RTK, PPP, corrections, authentication, and multi-constellation support.
