        name - name of the State Transition Matrix additional state
        parameters - selected parameters for Jacobian computation
    • Method Detail

      • getConversionJacobian

        protected double[][] getConversionJacobian​(SpacecraftState state)
        Get the conversion Jacobian between state parameters and parameters used for derivatives.

        For DSST and TLE propagators, state parameters and parameters used for derivatives are the same, so the Jacobian is simply the identity.

        For Numerical propagator, parameters used for derivatives are cartesian and they can be different from state parameters because the numerical propagator can accept different type of orbits.

        Overrides:
        getConversionJacobian in class JacobiansMapper
        Parameters:
        state - spacecraft state
        Returns:
        conversion Jacobian
