Studying the static errors of MEMS accelerometer triad in quasiharmonic oscillation mode

Abstract

The procedure proposed for studying the errors of MEMS accelerometer triad reduces the test duration as compared with traditional methods and allows estimation of mutual geometrical arrangement of sensors in the triad. The proposed approach consists in studying the static characteristics of sensors in oscillating angular motion mode and estimates error coefficients in mathematical model of accelerometer readings along with location of accelerometer triad in the closed IMU casing. Results of studying the errors of MEMS accelerometer triad are presented.
