Class OrbitNatureConverter

java.lang.Object

fr.cnes.sirius.patrius.stela.orbits.OrbitNatureConverter

public final class OrbitNatureConverter
extends Object

Converts a StelaEquinoctialOrbit from mean to osculating parameters, and reverse. Since the StelaEquinoctialOrbit does not contain a "mean" or "osculating" information flag, it is the user's responsibility to ensure a coherent use of this converter.

Constructor Detail

OrbitNatureConverter

public OrbitNatureConverter(List<StelaForceModel> inForceModels)

Default constructor.

Parameters:

inForceModels - list of force models used for conversion

Method Detail

toMean

public StelaEquinoctialOrbit toMean(StelaEquinoctialOrbit oscOrbit)
                             throws PatriusException

Converts an osculating StelaEquinoctialOrbit to a mean one.

Parameters:

oscOrbit - input osculating orbit

Returns:

a mean orbit equivalent to the osculating input orbit

Throws:

PatriusException - if a position computation fails

toOsculating

public StelaEquinoctialOrbit toOsculating(StelaEquinoctialOrbit meanOrbit)
                                   throws PatriusException

Converts a mean StelaEquinoctialOrbit to an osculating one.

Parameters:

meanOrbit - input mean orbit

Returns:

an osculating orbit equivalent to the mean input orbit

Throws:

PatriusException - if a position computation fails
