Method Detail

applyCorrection

public NormalizedGeodeticPoint applyCorrection(Vector3D satPos,
                                               Vector3D satLos,

                                               IntersectionAlgorithm algorithm)

Apply correction to the intersected point with an atmospheric refraction model.

Specified by:

applyCorrection in class AtmosphericRefraction

Parameters:

satPos - satellite position, in body frame

satLos - satellite line of sight, in body frame

rawIntersection - intersection point before refraction correction

algorithm - intersection algorithm

Returns:

corrected point with the effect of atmospheric refraction ExtendedEllipsoid.pointAtAltitude(Vector3D, Vector3D, double) or see IntersectionAlgorithm.refineIntersection(org.orekit.rugged.utils.ExtendedEllipsoid, Vector3D, Vector3D, NormalizedGeodeticPoint)
