Workspace Method refellipsoidOrbitPlane


Conversion of 3D ellipsoid to 2D orbit track geometry.

Determines an approximate reference ellipsoid following an orbit
track. The new ellipsoid is determined simply, by determining the
radius at the maximum latitude and from this value calculate a new
new eccentricity. The orbit is specified by giving the orbit
inclination (``orbitinc``), that is normally a value around 100 deg
for polar sun-synchronous orbits.
