- An
ellipsoid is a
surface that can be
obtained from a
sphere by
deforming it by
means of
directional scalings, or more generally, of an
affine transformation...
- the
angle formed between the
vector perpendicular (or normal) to the
ellipsoidal surface from the point, and the
plane of the equator. Two
levels of abstraction...
- An
Earth ellipsoid or
Earth spheroid is a
mathematical figure approximating the Earth's form, used as a
reference frame for com****tions in geodesy, astronomy...
- the
ellipsoid method is an
iterative method for
minimizing convex functions over
convex sets. The
ellipsoid method generates a
sequence of
ellipsoids whose...
-
Erdmessung (Central
Bureau of
International Geodesy), and a
series of
global ellipsoids of the
Earth were
derived (e.g.,
Helmert 1906,
Hayford 1910 and 1924)...
- the
motion of its
inertia ellipsoid,
which is
rigidly fixed to the
rigid body like a
coordinate frame. Its
inertia ellipsoid rolls,
without slipping, on...
- The
study of
geodesics on an
ellipsoid arose in
connection with
geodesy specifically with the
solution of
triangulation networks. The
figure of the Earth...
-
Ellipsoidal coordinates are a three-dimensional
orthogonal coordinate system ( λ , μ , ν ) {\displaystyle (\lambda ,\mu ,\nu )} that
generalizes the two-dimensional...
- surface.
Approximating the
figure of
Earth by an
Earth spheroid (an
oblate ellipsoid), the
radius ranges from a
maximum (equatorial radius,
denoted a) of nearly...
-
celestial body is
called a
reference ellipsoid. The
