Static and dynamic performance tests were conducted on three Sino-G5 relative gravimeters at the Jiugong Mountain national gravity baseline field, and the test data was analyzed. The results demonstrate that the instrument static data exhibits favorable linear characteristics, with dynamic measurement accuracy consistently better than 10 μGal, and the consistency among multiple instruments is also excellent. This indicates that the performance of the Sino-G5 gravimeter meets the requirements for high-precision gravity measurements in regional geophysical exploration.
