Siderust

Precision astronomy & orbit analysis libraries for embedded and research systems

See benchmarks: up to 14× faster than ERFA →

What we build

Siderust builds mission-critical astronomical computation and physical modeling libraries in pure Rust. From embedded spacecraft flight software to research-grade pipelines, validated against authoritative ephemerides, zero unsafe code, zero hidden allocations.

Performance First

Zero-cost abstractions and SIMD optimizations where it counts. Built for speed without sacrificing safety.

Type Safe

Leverage Rust's powerful type system for compile-time guarantees and fearless refactoring.

Well Documented

Comprehensive documentation with examples. We believe great docs are as important as great code.
