-
A.
GNSS reference network
A GNSS reference network is a coordinated system of continuously operating GNSS stations that provide precise, stable positioning and timing references for surveying, navigation, and geospatial applications.
-
B.
geodetic reference point
A geodetic reference point is a precisely surveyed physical location on the Earth's surface used as a fixed coordinate reference for mapping, surveying, and geospatial measurements.
-
C.
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.
-
D.
geodetic datum component
A geodetic datum component is an individual element (such as an ellipsoid, reference frame, or coordinate system parameter) that contributes to defining the position, orientation, and scale of a geodetic datum used for spatial referencing on or near the Earth’s surface.
-
E.
geodetic datum
chosen
A geodetic datum is a reference framework consisting of a defined origin, orientation, and scale used to precisely locate points on the Earth’s surface in terms of latitude, longitude, and elevation.
- 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.
