Domestic Absolute Gravimeter Cave Comparison Observation
摘要
Abstract
To further evaluate the technical performance of domestic independently developed absolute gravimeters,this study conducted comparison observations using multiple absolute gravimeters in the cave of the Huazhong University of Science and Technology National Gravimetry Laboratory.Through unified data processing,high-precision absolute gravity comparison data were obtained.The results demonstrate that no significant deviation exists between atomic interferometry absolute gra-vimeters and laser interferometry absolute gravimeters in this comparison,with deviations all within-4.95 μGal to 5.31 μGal.Each atomic interferometry absolute gravimeter achieved an observation precision of 1 μGal during continuous 4-hour measurements,with inter-instrument deviations main-tained below 10 μGal,demonstrating excellent stability and consistency.This study marks the first comparison measurements conducted on multiple domestically developed absolute gravimeters featu-ring independent domestic.It involved detailed data processing,scientific evaluation,and a multidi-mensional performance assessment,providing crucial references for the subsequent development and application of domestic gravimeters.关键词
