Interface PropagatorConverter

All Known Implementing Classes:

AbstractPropagatorConverter, FiniteDifferencePropagatorConverter, JacobianPropagatorConverter

public interface PropagatorConverter

This interface is the top-level abstraction for propagators conversions.

It provides a way to convert a given propagator or a set of SpacecraftState into a wanted propagator that minimize the mean square error over a time span.

Method Detail

convert

Propagator convert(Propagator source,
                   double timeSpan,
                   int nbPoints,
                   List<String> freeParameters)
            throws OrekitException

Convert a propagator into another one.

Parameters:

source - propagator to convert

timeSpan - time span considered for conversion

nbPoints - number of points for sampling over the time span

freeParameters - names of the free parameters

Returns:

adapted propagator

Throws:

OrekitException - if propagator cannot be adapted
