Package org.orekit.models.earth Description

This package provides models that simulate certain physical phenomena of Earth and the near-Earth environment.

Currently the following models are included:

Geoid

A Geoid is an equipotential surface of Earth's gravity field. This package provides the means to compute a Geoid from the gravity field harmonic coefficients, as in the following example. See the comment for Geoid for some important caveats.


 ReferenceEllipsoid ellipsoid
         = new ReferenceEllilpsoid(a, f, bodyFrame, GM, spin);
 Geoid geoid = new Geoid(
         GravityFieldFactory.getNormalizedProvider(degree, order),
         ellipsoid);
 double undulation = geoid.getUndulation(lat, lon, date);
