Abstract
An atomic gravimeter device includes one or more lasers and three or more atomic sources. The three or more atomic sources are disposed to launch or drop atoms vertically. The one or more lasers are disposed to generate laser beams that interact with sets of atoms from an atomic source of the three or more atomic sources to measure accelerations of the sets of atoms. A measured value is determined for gravity using interwoven acceleration measurements of the sets of atoms from the three or more atomic sources.
