Abstract

A single-axis rotational modulation SINS method based on four-gyro redundancy configuration is designed to solve the problem that the reliability of orthogonal configuration is not high and the navigation error is accumulated with time increasing quickly. For getting highest reliability

best navigation performance and higher precision under single fault condition

a four-gyro symmetrical and sideling redundancy configuration is proposed in a device level technology. Due to the advantage of single-axis rotational modulation for decreasing the constant device drift in the vertical direction

the redundancy configuration is combined with rotational modulation method creatively. The design method and process are also given in detail. The results show that the reliability of SINS can be increased by 75 % and the positioning precision can be improved by 32 %. The new method can improve navigation precision and reliability. Meanwhile

the gyroscopes in the configuration are symmetrical with easy installation

calibration and engineering implementation.
