N-vector
n
-vector
is a three parameter
non-singular
horizontal position representation
well-suited for replacing
latitude
and
longitude
in mathematical calculations and computer algorithms. Geometrically, it is a
unit vector
that is
normal
to the
reference ellipsoid
. The vector is
decomposed
in an
Earth centered earth fixed
coordinate system
. It behaves the same at all Earth positions, and it holds the mathematical
one-to-one
property.
