Method Detail

transformLOS

Vector3D transformLOS(int i,
                      Vector3D los,
                      AbsoluteDate date)

Transform a line-of-sight.

Parameters:

i - los pixel index

los - line-of-sight to transform

date - current date

Returns:

transformed line-of-sight

transformLOS

<T extends Derivative<T>> FieldVector3D<T> transformLOS(int index,
                                                        FieldVector3D<T> los,
                                                        AbsoluteDate date,
                                                        DerivativeGenerator<T> generator)

Transform a line-of-sight and its partial derivatives.

This method is used for LOS calibration purposes. It allows to compute the Jacobian matrix of the LOS with respect to the parameters, which are typically polynomials coefficients representing rotation angles. These polynomials can be used for example to model thermo-elastic effects.

Type Parameters:

T - derivative type

Parameters:

index - los pixel index

los - line-of-sight to transform

date - date

generator - generator to use for building DerivativeStructure instances

Returns:

line of sight, and its first partial derivatives with respect to the parameters

getParametersDrivers

Stream<ParameterDriver> getParametersDrivers()

Get the drivers for LOS parameters.

Returns:

drivers for LOS parameters
