Repeated Measurements of Gravity with the Absolute Gravimeter FG5 #210 at Matsushiro, Japan and Comparison with the Superconducting Gravimeter T011
Absolute gravity measurements have been repeatedly made with the FG5 #210 at the superconducting gravimeter station in Matsushiro, Japan. Four out of the five experiments so far performed were successful. The data from the absolute gravimeter are used to calibrate the instrumental sensitivity and drift of the superconducting gravimeter TO 11 with good results. Drift of the absolute gravimeter is investigated at the same time. Long-term gravity changes are discussed by collocating the data from the absolute and superconducting gravimeters.
