sidereon-core 0.9.1

The complete Sidereon engine: numerical astrodynamics propagation core plus the GNSS domain layer (SP3, broadcast ephemeris, multi-GNSS positioning, RTK/PPP, ionosphere/troposphere, DOP) behind a default-on gnss feature

//! Compact orbit approximations.
//!
//! Reduced orbits are fitted approximations for caching, transport, and quick
//! visibility math. They are not precise ephemeris products; use
//! [`crate::ephemeris::Sp3`] or [`crate::ephemeris::BroadcastEphemeris`] when
//! full-fidelity products are available.
