All Implemented Interfaces:

IOrbitalParameters, Serializable

public class ApsisAltitudeParameters
extends AbstractOrbitalParameters

This class handles periapsis altitude/apoapsis altitude parameters.

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

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

where Ω stands for the Right Ascension of the Ascending Node, v stands for true anomaly and req for central body radius (m)
