//! **spacelab-gnss** — multi-constellation GNSS broadcast orbits, observations, geometry metrics and
//! RINEX parsing.
//!
//! The Keplerian constellations (GPS/Galileo/BeiDou/QZSS/NavIC) broadcast a
//! Keplerian-plus-corrections model turned into an Earth-fixed state by the IS-GPS-200 algorithm
//! ([`gps`]); GLONASS instead broadcasts a PZ-90 Cartesian state integrated numerically ([`glonass`]).
//! [`rinex`] reads either out of a RINEX 3 navigation file, [`almanac`] reads the coarse,
//! long-validity GPS almanac in both distributed formats, and [`dop()`] turns a set of satellite
//! positions into the dilution-of-precision geometry metrics.
//!
//! The measurement side starts at [`rinex_obs`], which reads a RINEX 3 observation file:
//! [`combinations`] forms the dual-frequency linear combinations from those observables,
//! [`cycle_slip`] cuts a carrier-phase arc where its integer ambiguity jumped, and [`lambda`] solves
//! the integer least-squares problem that fixes the ambiguity itself.
//!
//! This exceeds Orekit's `GNSSPropagator` reach: all six constellations plus the DOP metrics GNSS
//! engineers actually use. The orbit math is `no_std` + `libm`; the text parser needs `std`.
