Cold Atomic Gravimeter is a quantum precision measurement product developed by LONTEN with complete independent intellectual property rights. It uses free falling cold atomic clusters in an ultra-high vacuum environment as the quality inspection, and uses laser precision to manipulate the splitting, state inversion, and beam merging of cold atomic matter waves, thereby forming interference of cold atomic matter waves. Finally,the gravitational acceleration value is obtained by measuring the phase shift of the matter wave, which is a new type of absolute gravimeter. A-Grav consists of two main parts: a detection unit and a control unit. The detection unit is used to sense the acceleration of gravity, and the control unit is used to provide the photoelectric, timing module, data processing, and output functions required in the gravity measurement process.

The product application A-Grav can work continuously without interruption and is suitable for various scenarios from fixed-point measurement to mobile exploration. It can be widely used in geological hazard monitoring, geodetic surveying, resource exploration, buried object detection, gravity assisted navigation and other fields.
