Constructor Detail

IonosphericGradientConverter

public IonosphericGradientConverter(SpacecraftState state,
                                    int freeStateParameters,
                                    AttitudeProvider provider)

Simple constructor.

Parameters:

state - regular state

freeStateParameters - number of free parameters, either 3 (position) or 6 (position-velocity)

provider - provider to use if attitude needs to be recomputed

Method Detail

getFreeStateParameters

public int getFreeStateParameters()

Get the number of free state parameters.

Overrides:

getFreeStateParameters in class AbstractGradientConverter

Returns:

number of free state parameters

getState

public FieldSpacecraftState<Gradient> getState(IonosphericModel ionoModel)

Get the state with the number of parameters consistent with ionospheric model.

Parameters:

ionoModel - ionospheric model

Returns:

state with the number of parameters consistent with ionospheric model

getParameters

public Gradient[] getParameters(FieldSpacecraftState<Gradient> state,
                                IonosphericModel ionoModel)

Get the ionospheric model parameters.

Parameters:

state - state as returned by getState(IonosphericModel)

ionoModel - ionospheric model associated with the parameters

Returns:

ionospheric model parameters
