Constructor with number of points used for interpolation

Parameters:

inAttitudes - the list of attitudes. WARNING : these attitudes must be ordered.

nbInterpolationPoints - number of points used for interpolation

Throws:

PatriusException - if the number of point is too small for interpolating

TabulatedSlew

public TabulatedSlew(List<Attitude> inAttitudes,
                     String natureIn)

Method Detail

getAttitude

public Attitude getAttitude(AbsoluteDate date,
                            Frame frame)
                     throws PatriusException

Compute the attitude.

Specified by:

getAttitude in interface Slew

Parameters:

date - : current date

frame - : reference frame from which attitude is computed

Returns:

attitude : attitude at the specified date

Throws:

PatriusException - orekit exception

getAttitude

public Attitude getAttitude(PVCoordinatesProvider pvProvider,
                            AbsoluteDate date,
                            Frame frame)
                     throws PatriusException

Compute the attitude corresponding to an orbital state.

pvProvider is unused since slew has been computed beforehand.

Specified by:

getAttitude in interface AttitudeProvider

Overrides:

getAttitude in class TabulatedAttitude

Parameters:

pvProvider - local position-velocity provider around current date

date - current date

frame - reference frame from which attitude is computed

Returns:

attitude attitude on the specified date and position-velocity state

Throws:

PatriusException - if attitude cannot be computed for provided date

getSpinDerivatives

public Vector3D getSpinDerivatives(AbsoluteDate date,
                                   Frame frame)
                            throws PatriusException

Get spin derivatives.

Parameters:

date - the date to compute derivative of spin

frame - reference frame from which derivative of spin is computed

Returns:

the spin derivative

Throws:

PatriusException - if spin derivative cannot be computed

copy

public TabulatedSlew copy(AbsoluteDateInterval newIntervalOfValidity)

Creates a new leg from this one.

Specified by:

copy in interface AttitudeLeg

Specified by:

copy in interface Slew

Specified by:

copy in interface Leg

Overrides:

copy in class TabulatedAttitude

Parameters:

newIntervalOfValidity - The time interval of the leg to create

Returns:
