Reference Frame Conversion — Worked Example

Direct answer

Reference Frame Conversion — Worked Example is implemented as a source-bounded worked example guide.

Answer contract

Apply the worked example lens only to the exact inspected source scope; do not infer authority from adjacent topics.

Evidence and exact locators

t22-quarter-turn-frame — lib/federation/readiness-tranche-22.ts — rotateCartesianQuarterTurns. Supports: Performs exact Cartesian rotations in integer quarter turns with a normalized transform identifier.

src-iers-reference-frames — Chapter 5, transformation between the ITRS and GCRS. Supports: Specifies the sequence and quantities used to transform between terrestrial and celestial reference systems.

What the evidence does not establish

This is a synthetic two-dimensional orthogonal transform, not an Earth-orientation, celestial, geodetic, epoch, or uncertainty service.

Does not establish that a software implementation uses the correct epoch, Earth-orientation parameters, units, or convention version.
