TLEPropagatorBuilder

public TLEPropagatorBuilder(int satelliteNumber,
                    char classification,
                    int launchYear,
                    int launchNumber,
                    String launchPiece,
                    int elementNumber,
                    int revolutionNumberAtEpoch)
                     throws OrekitException

Build a new instance.

Parameters:

satelliteNumber - satellite number

classification - classification (U for unclassified)

launchYear - launch year (all digits)

launchNumber - launch number

launchPiece - launch piece

elementNumber - element number

revolutionNumberAtEpoch - revolution number at epoch

Throws:

OrekitException - if the TEME frame cannot be set

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)

setParameter

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

Specified by:

setParameter in interface ParameterizedODE

Throws:

IllegalArgumentException
