Atomic Gravimeter Based on Atom Interferometry Being Developed at KRISS

Abstract

We present the current status of an atomic gravimeter being developed at KRISS for precise absolute gravity measurement. The gravimeter is based on atom interferometry with laser cooled 87Rb atoms. The short-term stability of the gravity measurement is $1.6\times 10^{-8}$ at 1 s average time. Analysis on short-and long-term stability of the gravimeter is discussed.
