| Abstract: | Micro-tremble measuring technique based on total accelerometer inertial measurement unit is researched and analyzed. Measurement unit is designed and experimental model machine is developed. Inertial measurement unit consists of nine accelerometers. This paper derives specific gravity equation of accelerometer and forwards an algorithm combined of intergration and extraction of root to solve angular velocity. Computation method using quaternion computation of srrapdown matrix and computation method of arbitrary position at arbitrary time in inertial reference system are given. |
