Author: Giuseppe Colucci On doy 2017/284 the NOT1 (Noto, Italy) station has been upgraded. New Leica GR30 replaced old Trimble 4000ssi receiver and new Leica AR20 replaced old Trimble Choke Ring antenna. New receiver produces Rinex 3 data files too. Updated sitelog has been submitted to EUREF/IGS. Best regards, Giuseppe Colucci
