Method Detail

getName

String getName()

Get the name of the additional state.

Returns:

name of the additional state

computeDerivatives

void computeDerivatives(StelaEquinoctialOrbit o,
                        double[] p,
                        double[] pDot)
                        throws OrekitException

Compute the derivatives related to the additional state parameters.

Parameters:

o - current orbit information: date, kinematics

p - current value of the additional parameters
