Geodetic Observation:
Measure Gravity with Atoms

Quantum gravimetry measures the acceleration of gravity, by using freely falling atoms as test masses. Gravimeters employing quantum mechanical techniques comprise the newest class of instruments, and they promise to combine the best characteristics of classical absolute and relative gravimeters.

Quantum gravimeters have been in development for about 30 years, and the technology is mature enough that commercial devices are now available.
