Method Detail

radiationPressureAcceleration

Vector3D radiationPressureAcceleration(SpacecraftState state,
                                       Vector3D flux)
                                throws PatriusException

Compute the acceleration due to radiation pressure.

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 acceleration in the same inertial frame as spacecraft orbit (m/s²)

Throws:

PatriusException - if acceleration cannot be computed

                      Vector3D satSunVector)
               throws PatriusException

Compute acceleration derivatives with respect to additional parameters.

Parameters:

s - spacecraft state

param - the parameter with respect to which derivatives are required

Parameters:

s - spacecraft state

dAccdPos - acceleration derivatives with respect to position parameters

dAccdVel - acceleration derivatives with respect to velocity parameters

satSunVector - satellite to sun vector, expressed in the spacecraft frame

Throws:

PatriusException - if derivatives cannot be computed
