A thorough understanding of the static drift characteristics of CG6 relative gravimeter is crucial for obtaining high-quality relative gravity observation data. We utilize 65-hours observation data from CG6-90 relative gravimeter and iGrav-56 superconducting gravimeter installed on adjacent site at the Sanya seismic station. Three calculation schemes are designed to determine the static drift rate of CG6-90 relative gravimeter. The results show that CG6-90 relative gravimeter exhibits a static linear drift rate of -8.861±0.035 μGal/h, and there is a nonlinear drift phenomenon with gravity variation ranging from -1 to 1 μGal. When calculating the static drift rate of CG6 relative gravimeter, it is essential to apply corrections for gravity changes induced by solid Earth tides, ocean tides, and atmospheric pressure variations.

深入认识CG6相对重力仪的静态漂移特性有利于获得高质量的相对重力观测数据。利用三亚地震台相邻2个重力观测墩上的CG6-90相对重力仪和iGrav-56超导重力仪65 h观测数据, 设计3种方案计算CG6-90相对重力仪的静态漂移率。结果表明, CG6-90相对重力仪的静态线性漂移率为-8.861±0.035 μGal/h, 仪器观测数据存在-1~1 μGal重力变化的非线性漂移现象, 并且计算CG6相对重力仪静态漂移率时有必要进行固体潮、海潮和气压变化等因素导致的重力变化改正。
