Method Detail

computeSpinByFD

default double computeSpinByFD(PVCoordinatesProvider pvProv,
                               AbsoluteDate date,
                               double computationStep)
                        throws PatriusException

Compute the orientation derivative at a given date by finite differences (using 2nd order centered finite differences). Time interval boundaries are properly taken into account.

Specified by:

computeSpinByFD in interface OrientationAngleProvider

Parameters:

pvProv - PV Coordinates Provider.

date - Date at which the orientation derivative is desired.

computationStep - Computation step used for the finite differences (in seconds).

Returns:

The orientation derivative of the satellite

Throws:

PatriusException - When the orientation cannot be computed

computeSpinDerivativeByFD

default double computeSpinDerivativeByFD(PVCoordinatesProvider pvProv,
                                         AbsoluteDate date,
                                         double computationStep)
