The n-vector framework uses the normal vector to the Earth ellipsoid
(called n-vector) as a non-singular position representation that turns out to
be very convenient for practical position calculations.
The n-vector is simple to use and gives exact answers for all global positions,
and all distances, for both ellipsoidal and spherical Earth models.
This package is a translation of the 'Matlab' library from FFI,
the Norwegian Defence Research Establishment, as described in Gade (2010)
nvctr package implements the n-vector approach to geographical
position calculations using an ellipsoidal model of Earth as described
in (Gade 2010).
You can install the development version of
or the CRAN version (when this package will land to CRAN):
nvctr can be used to solve geographical position calculation like
