现代弹道式重力仪的工作原理是基于测量宏观测试体或冷原子云在重力场中的运动参数,并使用来自测试体运动方程的测量的运动参数计算自由落体加速度。世界上大约有200台可移动的弹道重力仪,其中最好的不确定度为10−8 ms−2。绝对重力仪计量保证体系正在研制中。绝对重力仪的改进将使其能在移动平台上使用。
Operating principle of modern ballistic gravimeters is based on the measurement of motion parameters of a macroscopic test body or a cloud of cold atoms in the gravity field and calculation of free-fall acceleration using the measured motion parameters from the test body motion equation. There are about 200 transportable ballistic gravimeters in the world, the best of which feature uncertainty of a few units of 10−8 ms−2. Metrological assurance system for absolute gravimeters is being developed. Improvements in absolute gravimeters will allow their use on moving platforms.
