Optomechanical inertial sensors
Applied Optics, 2020 We present a performance analysis of compact monolithic optomechanical inertial sensors that describes their key fundamental limits and overall acceleration noise floor. Performance simulations for low-frequency gravity-sensitive inertial sensors show attainable acceleration noise floors on the order of 1 × 10 −

A Calibration Algorithm for Microelectromechanical Inertial Sensors
Известия высших учебных заведений России: Радиоэлектроника, 2022 Introduction. Systematic errors of microelectromechanical (MEMS) inertial sensors, such as those related to zero drift, scale factor, and nonorthogonality of sensitive axes, are the main sources of errors in strapdown inertial navigation systems (SINS ...
