ASSESSMENT OF ACCURACY OF NONORTHOGONAL REDUNDANT INERTIAL MEASURING INSTRUMENTS

SUMMARY

The paper deals with features of accuracy assessment of nonorthogonal redundant measuring instruments based on inertial sensors. The nonorthogonal redundant measuring instrumental based on the inertial units are developed. Approaches to assessment procedure both for measuring instruments based on single inertial sensors and triaxial inertial units are represented. Tables of directional cosines between the inertial and measuring reference frames are obtained. Analysis of measuring accuracy of the nonorthogonal redundant measuring instruments is carried out. Experimental results are given. The represented results can be applied in control systems of unmanned moving vehicles.
