Target entity: Terrestrial Dynamical Time Context triple: [Ephemeris Time, replacedBy, Terrestrial Dynamical Time]
-
A.
Barycentric Dynamical Time
Barycentric Dynamical Time is a relativistic time scale used in celestial mechanics and ephemerides, defined for an observer at the solar system’s barycenter to accurately model planetary and spacecraft motions.
-
B.
Terrestrial Time
chosen
Terrestrial Time is a modern astronomical time standard used for precise calculations of planetary motion and ephemerides, defined in relation to atomic time rather than Earth's rotation.
-
C.
Ephemeris Time
Ephemeris Time is a former astronomical time standard based on the orbital motion of the Earth around the Sun, used to provide a uniform measure of time before being replaced by more precise atomic-based scales.
-
D.
Coordinated Universal Time
Coordinated Universal Time (UTC) is the primary global time standard by which the world regulates clocks and time, serving as the basis for most civil time zones.
-
E.
International Terrestrial Reference System
The International Terrestrial Reference System is a globally standardized, Earth-centered coordinate framework used for precise positioning, navigation, and geodetic measurements.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
