public class OrbitSolver
extends Object

Calculations for Keplerian Orbits.

Based on: J. Kepler, "Astronomia Nova" (1609) and "Harmonices Mundi" (1619).

Implements orbital mechanics calculations using the six classical Keplerian orbital elements and transformations between perifocal and inertial reference frames.
