Abstract
The performance of MEMS gyroscope is crucial to its application, and the zero-bias stability is the main characteristic parameter of gyroscope performance. When fusing several outputs of similar MEMS gyroscope, we often use the weighted mean method. The weight has great influence on the fusing result. In this paper, the optimal weight choice used in the fusion of Multi-MEMS gyroscope data is derived based on multivariate numerical theory. Experimental results show that after simulating multi-MEMS gyroscope data fusion on the measurement result of several gyroscopes, the zero-bias stability will effectively improve.
