【 摘 要 】

To solve the complex vibration testing six degree-of-freedom rigid space problem, this paper designs a sensor array configuration model and corresponding algorithm. The model integrating the method of integration and the method of the square calculates the angular velocity data. Through the analysis of the inner link of data in sensor output equation, the calculating data updates and iterations constantly, maintaining understanding of real-time and accuracy of calculation data. At the same time it can solve the problem of the error accumulation of integral method and extraction of the problem of misjudgement of symbols. The simulation results show that the error is always within the range of 10-4 in 1000 seconds.
