Target class: Terrestrial reference frame Context triple: [ITRF2020, instanceOf, Terrestrial reference frame]
-
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.
global reference frame
A global reference frame is a fixed, overarching coordinate system used to consistently define positions, orientations, and motions of objects throughout an entire modeled world or environment.
-
D.
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.
-
E.
terrestrial navigation system
A terrestrial navigation system is a ground-based infrastructure and associated equipment that determine a vehicle’s position, velocity, and course using signals or references located on or near the Earth’s surface.
- 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.
