-
A.
component of the International Earth Rotation and Reference Systems Service
A component of the International Earth Rotation and Reference Systems Service is an organizational unit or subsystem that contributes specific data, analysis, or operational functions to support the monitoring, prediction, and standardization of Earth rotation and reference frames.
-
B.
Earth orientation parameter service
A service that provides precise, time-varying measurements and predictions of Earth’s orientation in space—such as polar motion, UT1-UTC, and nutation—used to transform between terrestrial and celestial reference frames.
-
C.
IERS product center
chosen
The IERS product center is an organizational unit within the International Earth Rotation and Reference Systems Service responsible for generating, maintaining, and distributing specific geodetic and astronomical reference products such as Earth orientation parameters and reference frame realizations.
-
D.
astrometric standard
An astrometric standard is a celestial object with precisely known position and motion used as a reference to calibrate and validate astrometric measurements.
-
E.
edition of IERS Conventions
An edition of the IERS Conventions is a specific, dated version of the International Earth Rotation and Reference Systems Service guidelines that standardize models, constants, and procedures for precise Earth orientation and reference frame applications.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
