All Implemented Interfaces:

IOrbitalParameters, Serializable

public class ApsisRadiusParameters
extends AbstractOrbitalParameters

This class handles periapsis/apoapsis parameters.

The parameters used internally are the apsis elements which can be related to keplerian elements as follows:

• periapsis = a (1 - e)
• apoapsis = a (1 + e)
• i
• ω
• Ω
• v

where Ω stands for the Right Ascension of the Ascending Node and v stands for true anomaly
