- Sidereon provides a Rust core for GNSS and astrodynamics, including SGP4, SPP/RTK/PPP, RINEX, observation quality control, RTCM/NTRIP streams, frames/time, ionosphere, and conjunction calculations.
- The engine is verified against reference implementations like Vallado, Skyfield, IGS, teqc, and IERS.
- It supports idiomatic interfaces in Rust, Python, C, Elixir, and WebAssembly, with a single verified codebase across languages.
- The engine runs client-side in browsers via WebAssembly, enabling real-time calculations (global coverage, close-approach screening, orbit determination) without server calls.
- Cargo installation is available via 'cargo add sidereon' and crates.io.
