Today we carried out the survey for the measurement of the position of the NCal reference plate points @NE, placed in the SE, NE and NW part of the tower.

Tab.1 reports the VRS coordinates obtained for the points measured (Fig.1), considering NCal_XX_01 as the internal point and NCal_XX_02 as the external one.

Fig.1 to 9 show some photos of the three stations arranged for the survey and the scheme of the points.
