Compact Accelerometer for Inertial Navigation, Gravimetry and Gradiometry Based on Light Pulse Atom Interferometry
AOSense, Inc. proposes to design a compact proof-of-concept accelerometer based on light-pulse atom interferometry for use in inertial navigation, gravimetry and gravity gradiometry. Inertial sensing by atom interferometry promises exceptional sensitivity, stability and absolute calibration. We will conduct trade studies of sensor performance versus sensor size, complexity and power, and evaluate the design via error modeling and simulations of sensor performance. Simulations will include intrinsic sensor errors and sensitivity to environmental variations. Anticipated acceleration sensitivity is<1 ng/sqrt(Hz), bias instability<10 ng, and scale factor instability<0.001 ppm.
