== Introduction ==

=== Scope ===
The "Orbital parameters" package contains classes to represent the orbital state of a space object. Several types of parameters are available (cartesian, keplerian, equinoctial... with different position angle definitions : true, mean, eccentric).
Orbital parameters do not define a date nor a frame. To fully define an orbit, including date and frame, please refer to [FDY_Orbits_Home Orbits].

=== Javadoc ===
The classes for orbital parameters description are available in the package <code>org.orekit.orbits.orbitalparameters</code> of OREKIT.

|=Library|=Javadoc
| Orekit|[{{JavaDoc3.3}}/org/orekit/orbits/orbitalparameters/package-summary.html Package org.orekit.orbits.orbitalparameters]

=== Package Overview ===
All different orbital parameters types extend the abstract class AbstractOrbitalParameters and implement the interface IOrbitalParameters.

[[File:orbitalparameters.png|center]]

All conversions methods from one type to another are specifically handled by each type of orbital parameters, thus optimising conversions.

== Features Description ==
=== Available parameters ===
The available parameters types are :
* Cartesian : X, Y, Z, Vx, Vy, Vz
* Keplerian : a, e, i, perigee argument, right ascension of ascending node, anomaly (in each position angle types)
* Equinoctial : a, ex, ey (eccentricity vector), hx, hy (inclination vector), longitude argument (in each position angle types)
* Stela Equinoctial : a, ex, ey (eccentricity vector), ix, iy (inclination vector), mean longitude argument
* Circular : a, ex, ey (eccentricity vector), i, right ascension of ascending node, latitude argument (in each position angle types)
* Apsis (using radius) : periapsis, apoapsis, i, perigee argument, right ascension of ascending node, anomaly (in each position angle types)
* Apsis (using altitude) : altitude of periapsis, altitude of apoapsis, i, perigee argument, right ascension of ascending node, anomaly (in each position angle types)
* Equatorial : a, e, longitude of the periapsis (ω + Ω), ix (first component of inclination vector), iy (second component of inclination vector), anomaly (in each position angle types)
* Reentry : altitude, latitude, longitude, velocity norm, slope of velocity, azimuth of velocity

== Getting Started ==
Any orbital parameters can be defined using the chosen constructor. Here is an example using circular parameters and true anomaly:

<syntaxhighlight lang="java">
final CircularParameters circularParameters = new CircularParameters(10000E3, 0.1, 0.2, 0.3, 0.4, 0.5, PositionAngle.TRUE, Constants.EGM96_EARTH_MU);
</syntaxhighlight>

Then conversions to any orbital parameters type can directly be obtained using the conversion routines. Here is an example of conversion to equinoctial parameters:

<syntaxhighlight lang="java">
final EquinoctialParameters equinoctialParameters = circularParameters .getEquinoctialParameters();
</syntaxhighlight>
