The application of microminiature inertial measurement unit to the measurement of ejection movement parameters

The microminiature inertial measurement unit (MIMU), a new style of the inertial measurement system, has many advantages compared with the traditional IMU, such as small size, light weight, low cost, little power consumption, high bearing capacity and long life. Undoubtedly, it will have wider applications in military and commercial fields. However, it is a pity that current micro inertial sensors do not have enough accuracy. Therefore, the applications of the MIMU were limited to some extent. This paper describes a MIMU and its system composition, operating theory and error control technique. In addition, its application to the measurement of ejection movement parameters (missile launch from an aircraft) is introduced. Finally, its performance and further applications are evaluated
