nvctr: The n-vector Approach to Geographical Position Calculations
using an Ellipsoidal Model of Earth
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)
