Constructor Detail

JacobianPropagatorConverter

public JacobianPropagatorConverter(NumericalPropagatorBuilder builder,
                                   double threshold,
                                   int maxIterations)
                            throws OrekitException

Simple constructor.

Parameters:

builder - builder for adapted propagator, it must be configured to generate OrbitType.CARTESIAN states

threshold - absolute threshold for optimization algorithm

maxIterations - maximum number of iterations for fitting

Throws:

OrekitException - if the builder orbit type is not OrbitType.CARTESIAN
