Mobile gravimetry is an important technique in metrology, navigation, geodesy and geophysics. Although atomic gravimeters are presently used for accuracy, they are constrained by instrumental fragility and complexity. In a new study, Xuejian Wu and an interdisciplinary research team in the departments of physics, the U.S. Geological Survey, molecular biophysics and integrated bio-imaging, demonstrated a mobile atomic gravimeter. The device measured tidal gravity variations in the lab and surveyed gravity in the field.
