Miniature absolute gravimeter for long-term gravity surveys

Absolute gravimeters tie their measurement of gravity to the definition of the second 
by interrogating the position of a falling test mass using a laser interferometer. Our vision is to develop and prototype a miniaturised absolute gravimeter by 
leveraging modern vacuum, laser, and micro-electromechanical systems.
