Abstract

The absolute gravity measurement by FG5 was performed for the first time after starting continuous gravity observation by iGrav SG (# 017) at the Teshikaga Observatory, Hokkaido University. From the comparison between the absolute gravity value obtained with FG5 and the output value of iGrav SG, the scale factor in Medium Feedback mode of iGrav SG was estimated to be -1998 μGal/V (×10-8 ms-2/V).
