Domain Language¶

This page fixes the durable vocabulary used across the navigation handbook.

Orbit State¶

Typed satellite position, velocity, clock, and uncertainty information derived from broadcast ephemeris or precise products.

A file or message family whose payload encodes GNSS navigation truth rather than generic repository metadata. Examples include LNAV, CNAV, FNAV, INAV, SP3, CLK, ANTEX, and bias SINEX.

Correction Law¶

Reusable GNSS-domain computations such as ionosphere, troposphere, code and phase bias application, group delay handling, and signal combinations.

Estimator Behavior¶

The rules by which position, integrity, PPP, or RTK solvers interpret observations and evidence to produce or refuse a solution.

Runtime-Neutral¶

Behavior that depends on scientific inputs and configuration, but not on the live scheduling, channel ownership, or operator transport used by downstream packages.

Time Interpretation¶

GNSS-system-specific handling of weeks, rollovers, offsets, and civil-time relationships that exceed the foundational time contracts in bijux-gnss-core.
