Method Detail

radiationWrench

Wrench radiationWrench(SpacecraftState state,
                     Vector3D flux)
                       throws PatriusException

Compute the torque due to radiation pressire.

The computation includes all spacecraft specific characteristics like shape, area and coefficients.

Parameters:

state - current state information: date, kinematics, attitude

flux - radiation flux in the same inertial frame as spacecraft orbit

Returns:

spacecraft torque expressed at the mass center in the frame of the main part of the assembly (accounts for attitude)

Throws:

PatriusException - if torque cannot be computed

Wrench radiationWrench(SpacecraftState state,
                     Vector3D flux,
                     Vector3D origin,
                     Frame frame)
                       throws PatriusException

Compute the torque due to radiation pressire.

The computation includes all spacecraft specific characteristics like shape, area and coefficients.

Parameters:

state - current state information: date, kinematics, attitude

flux - radiation flux in the same inertial frame as spacecraft orbit

origin - point in which to express torque

frame - the reference frame

Returns:

spacecraft torque expressed at origin in frame

Throws:

PatriusException - if torque cannot be computed
