Atom Strapdown: Toward Integrated Quantum Inertial Navigation Systems

Abstract We present an alternative technique for estimating the response of a cold atom interferometer (CAI). Using data from conventional inertial measurement unit (IMU) and common strapdown terminology, position wave packet is tracked in newly introduced sensor frame, enabling hybridization both systems terms acceleration angular rate measurements. The frame allows easier mathematical description CAI integration into higher-level navigation systems. dynamic resulting transformation IMU are evaluated simulations. implementation method as prediction model extended Kalman filter explained demonstrated realistic simulations, showing improvements over two orders magnitude with respect to solution. Finally, implications these findings future hybrid quantum discussed.
