WebNov 22, 2024 · As a novel instrument for measuring absolute gravity, the atom gravimeter has shown high sensitivity and stability in the past three decades. In this work, we report a car-based portable atom gravimeter whose sensitivity is at the level of 1. 9 m G a l / H z (1 Gal = 0.01 m/s 2) both for lab and outdoor measurements.Its resolution can reach 30 … The modern gravimeter was developed by Lucien LaCoste and Arnold Romberg in 1936. They also invented most subsequent refinements, including the ship-mounted gravimeter, in 1965, temperature-resistant instruments for deep boreholes, and lightweight hand-carried instruments. Most of their designs remain in use with refinements in data collection and data processing.
