-
A.
Airy Modified ellipsoid
chosen
The Airy Modified ellipsoid is a slightly adjusted version of the Airy ellipsoid used as the reference surface for mapping and geodetic calculations in systems such as the Irish grid reference system.
-
B.
Earth gravity model
The Earth gravity model is a mathematical representation of Earth's gravitational field used for precise positioning, navigation, and geodetic calculations.
-
C.
WGS84
WGS84 is the global geodetic reference system and standard coordinate framework used for GPS and most modern mapping applications.
-
D.
IERS Conventions
IERS Conventions are a set of internationally recognized technical standards and models that define how to precisely measure and reference Earth’s rotation, orientation, and reference frames for geodesy and astronomy.
-
E.
Jacobi ellipsoid
A Jacobi ellipsoid is a rotating, self-gravitating fluid body in equilibrium that takes on a triaxial ellipsoidal shape due to its rapid spin.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
