Abstract:The absolute gravity acceleration measurement based on the cold atom interference principle has the advantages of high sensitivity and long-term continuous measurements. It is of great significance in basic physics research, resource exploration, and inertial navigation, and is recognized as the next generation of absolute gravimeter. This article describes the principle of atomic interferometric gravimetry, summarizes the hardware system composition and performance requirements, points out the main factors limiting the capability of measurement and engineering applications, and summarizes the current situation and future trend of the engineering development of atomic gravimeter.
