public class CustomVehicleSurfaceModel
extends Object
implements org.orekit.parameter.IParamDiffFunction

Vehicle surface model class. It defines a derivative function parameterizable where the variable is the spacecraft state and the function is the cross section surface (including solar panels) as seen from the velocity vector direction. It includes a multiplicative factor as a parameter.

CustomVehicleSurfaceModel

public CustomVehicleSurfaceModel(org.apache.commons.math3.geometry.euclidean.threed.CrossSectionProvider vehicleShape)

Creates a new instance without solar panels. It throws a runtime exception if the vehicle shape is null. It assumes a multiplicative factor of 1.0.

Parameters:

vehicleShape - vehicule's shape.

public CustomVehicleSurfaceModel(org.apache.commons.math3.geometry.euclidean.threed.CrossSectionProvider vehicleShape,
                         CustomParallelepiped solarPanels)

Creates a new instance with solar panels. It throws a runtime exception if the vehicle shape is null. It assumes a multiplicative factor of 1.0.

Parameters:

vehicleShape - vehicule's shape

solarPanels - solar panels shape (it may be null)

                         CustomParallelepiped solarPanels,
                         double multiplicativeFactor)

Creates a new instance with solar panels. It throws a runtime exception if the vehicle shape is null.

Parameters:

vehicleShape - vehicule's shape

solarPanels - solar panels shape (it may be null)

multiplicativeFactor - multiplicative factor for the total vehicle surface

Method Detail

value

public double value(org.orekit.propagation.SpacecraftState state)
