Studying the Accuracy Characteristics of Q-flex Accelerometers for Modernization of SINS

A technique has been developed for determining the precision parameters of accelerometers on a two-axis stand (TS) for imitating spatial motion. Its application allows us to reduce the time of calibration of individual inertial sensors, as well as to collect data during dynamic temperature measurement. The paper presents the results of calculations of the main parameters of accelerometers of the Q-flex type, obtained on the basis of experimental data. A mathematical estimate of the navigation error arising due to the presence of errors in accelerometers is presented. Due to the mathematical assessment of navigation errors, the suitability of using accelerometers on moving objects is determined.
