Abstract
In the paper the technological features, measuring principle and the test observations at Baijiatong were introduced in detail. At the same time, the calibration items along with the calibrations of two more relative gravimeters for gradient measurement, CG5/442 and CG5/444, which are applied to form a complete set of the absolute gravimeter, were also described and analyzed. Results show that, 2 sets of CG5 can fully satisfy the demands of specifications, and the standard deviation of FG5 test measurements is better than 2.0 ×10^-8ms^-2, which means that the whole set of the FG5 absolute gra vimeter can be applied in the absolute gravimetry of a part of bench stations in the Land Gravity Network Project.关键词
