Continuous observations by superconducting gravimeter

Relative superconducting gravimeter OSG-050 manufactured by GWR Instruments, Inc. USA. It provides continuous measurement of gravity variations with sampling rate of 1 sec at the gravimetric station Pecny since 2007. Data are distribued to IGETS (International Geodynamics and Earth Tide Service).由美国GWR仪器公司（GWR Instruments, Inc.）生产的OSG-050型相对超导重力仪，自2007年起便在佩奇尼重力测量站（Pecny）以1秒的采样率连续监测重力变化，相关数据已提交至国际地球动力学与固体潮服务中心（International Geodynamics and Earth Tide Service，简称IGETS）。
