Abstract: This article deals with accuracy research of the non-orthogonal configuration of inertial sensors based on Allan variance. The influence of changes in the measurement range of the inertial module on the Allan variance was assessed. Based on an analysis of the results of the Allan variance assessment, a procedure for choosing multi-axis MEMS sensors with identical characteristics to create an inertial non-orthogonal measuring instrument is proposed. An example of compiling a data processing algorithm for an inertial measuring instrument with a non-orthogonal arrangement of sensitivity axes based on an assembly of 3-axis MEMS sensors is given. The simulation results for numerical estimates are represented. Improvement of the accuracy of the non-orthogonal inertial measuring instruments using the Allan variance is shown.
