摘要：Specification, type, and IMU utilization on the INS algorithm influences rocket performance. Improvement could be done by hardware errors minimization that optimize algorithm and matrix transformation on the processor. Pitch angle (θ) on the Euler transform matrix have singularity on 90 degree. This paper modifies INS algorithm to solve that singularity. A novel control of rocket flight test with a modified algorithm which combines INS Euler and Quaternion method has been conducted. The modifications of INS algorithm proves that the proposed method can be used for flight test rocket that has a high-speed and rapid data alteration.
