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

FieldVector3D<DerivativeStructure> transformLOS(int index,
                                              FieldVector3D<DerivativeStructure> los,
                                              AbsoluteDate date)

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.

Parameters:

index - los pixel index

date - date

los - line-of-sight to transform

Returns:

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