fr.cnes.sirius.patrius.attitudes.slew.ConstantSpinSlewComputer

All Implemented Interfaces:

Serializable

public class ConstantSpinSlewComputer
extends Object
implements Serializable

Class for constant spin slew computation with angular velocity constraint. Computation of slew returns a ConstantSpinSlew.

The Constant spin slew is a "simple" slew that computes the attitude of the satellite using a spherical interpolation of the quaternions representing the starting and ending attitudes.
Like all the other attitude legs, its interval of validity has closed endpoints.

Method Detail

compute

public ConstantSpinSlew compute(PVCoordinatesProvider pvProv,
                                AttitudeProvider initialLaw,
                                AbsoluteDate initialDate,
                                AttitudeProvider finalLaw,
                                AbsoluteDate finalDate)
                         throws PatriusException

Compute the slew.

Parameters:

pvProv - satellite PV coordinates through time

initialLaw - initial attitude law (before the slew)

initialDate - slew start date (null if slew defined with its end date)

finalLaw - final attitude law (after the slew)

finalDate - slew end date (null if slew defined with its start date)

Returns:

built slew

Throws:

PatriusException - thrown if computation failed
