The atomic absolute gravimeter is a novel quantum gravity sensor that uses lasers to manipulate the interference of free-falling atoms in an ultra-high vacuum chamber and extracts absolute gravity acceleration information from the interference fringes.

Atomic gravimeters have no mechanical moving parts and can perform long-term continuous gravity observations.

Atomic gravity gradient meter is based on two atomic gravity meters placed vertically or horizontally to measure the gravity gradient value.
