org.orekit.propagation.semianalytical.dsst.forces.ForceModelContext
org.orekit.propagation.semianalytical.dsst.forces.DSSTGravityContext
Direct Known Subclasses:
DSSTTesseralContext, DSSTZonalContext
public class DSSTGravityContext extends ForceModelContext
This class is a container for the common parameters used in DSSTTesseral and DSSTZonal.

It performs parameters initialization at each integration step for the Tesseral and Zonal contribution to the central body gravitational perturbation.
