It is shown that, in the multiple LGS configuration proposed by Tallon & Foy (1990) used for the correction of the conical anisoplanatism, one can derive the correction for the conical anisokinetism effect also, provided that absolute tilt sensing is performed for only one of the various LGSs projected on the sky.
