Constructor Detail

KeplerianPropagatorBuilder

public KeplerianPropagatorBuilder(double mu,
                          Frame frame)

Build a new instance.

Parameters:

mu - central attraction coefficient (m³/s²)

frame - the frame in which the orbit is propagated (must be a pseudo-inertial frame)

Method Detail

buildPropagator

public Propagator buildPropagator(AbsoluteDate date,
                         double[] parameters)
                           throws OrekitException

Build a propagator.

Specified by:

buildPropagator in interface PropagatorBuilder

Parameters:

date - date associated to the parameters to configure the initial state

parameters - set of position/velocity(/free) parameters to configure the propagator

Returns:

an initialized propagator

Throws:

OrekitException - if propagator cannot be build

getFrame

public Frame getFrame()

Get the frame in which the orbit is propagated.

Specified by:

getFrame in interface PropagatorBuilder

Returns:

frame in which the orbit is propagated

setFreeParameters

public void setFreeParameters(Collection<String> parameters)
                       throws IllegalArgumentException

Set the free parameters in order to build the propagator.

The parameters must belong to the list returned by Parameterizable.getParametersNames()

Specified by:

setFreeParameters in interface PropagatorBuilder

Parameters:

parameters - free parameters to set when building the propagator

Throws:

IllegalArgumentException

getParameter

public double getParameter(String name)
                    throws IllegalArgumentException

Specified by:

getParameter in interface ParameterizedODE

Throws:

IllegalArgumentException

setParameter

public void setParameter(String name,
                double value)
                  throws IllegalArgumentException

Specified by:

setParameter in interface ParameterizedODE

Throws:

IllegalArgumentException
