Two Accelerometers Based Measurement Method for Rocket Rotation Angle and Analysis of its Theoretical Error

Real-time measurement of rocket rotation angle is needted to lower the shell distribution and to extend the range of rocket.A two-accelerometer based test method for measuring rocket rotation angle is put forward in this paper and its theoretical error is comprehensively analyzed.With its comparatively simple combination and data processing,the method tends to meet the requirement of real-time measurement,high reliability,low cost,and high feasibility.
