IMPROVING THE ACCURACY OF THE INERTIAL MEASUREMENT MODULE USING REDUNDANT MEASUREMENTS
Abstract
The work is devoted to the study of inertial measurement modules with a redundant structure. Various layouts of inertial meters in their composition are studied and the possibility of increasing accuracy through the use of redundant measurements is investigated. Block layouts with four, five, and six accelerometers, the measurement axes of which are directed along a cone, are considered. Also, a layout of six inertial meters, located with their measurement axes opposite each other, is considered. All the considered layouts are simulated and the output signal of the inertial measurement module is visualized. For the opposite layout, a semi-real-life experiment was conducted, with digital data recording and subsequent processing of the recorded output signal. It is shown that the oppsite layout has significant advantages, reducing both the systematic and random components of the measurement error.
