functiontheoreticalNormalGravityWGS84
WGS84 normal gravity over earth ellipsoid in negative y-direction
Extends from Modelica.Mechanics.MultiBody.Interfaces.partialGravityAcceleration (Interface for the gravity function used in the World object).
Information
Function that computes the theoretical gravity of the WGS84 ellipsoid earth model at and close to the earth ellipsoid surface, for the given "geodeticLatitude" and the given "height=r[2]" over the ellipsoid surface.
