Constructor Detail

EcksteinHechlerPropagatorBuilder

public EcksteinHechlerPropagatorBuilder(Frame frame,
                                UnnormalizedSphericalHarmonicsProvider provider)

Build a new instance.

Parameters:

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

provider - for un-normalized zonal coefficients

EcksteinHechlerPropagatorBuilder

public EcksteinHechlerPropagatorBuilder(Frame frame,
                                double referenceRadius,
                                double mu,
                                TideSystem tideSystem,

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
