Abstract

Gravimetric connection between SapporoGS and TsukubaFGS via ChitoseGS and HanedaGS with SCINTREX CG5 gravimeter S/N130141025 was carried out for instrument calibration. Observed relative gravity between SapporoGS and TsukubaFGS was 526mGal, which was the same as that of value determined by Geospatial Information Authority of Japan in order of 10-4. This measurement suggested that scale constant of this gravimeter is valid for below 500mGal difference with correction coefficient of 1.0002.
