I Introduction
The Inertial Measurement Unit (IMU) features advantages such as compact size, light weight, low power consumption, and high precision. It can be used to design pure strapdown, single-axis, and dual-axis modulated inertial navigation systems, meeting the demand for small-size, high-precision inertial navigation equipment in new unmanned platforms, underwater/torpedo weaponry, as well as land-based and airborne weapon platforms. It possesses the capability for dynamic measurement of carrier angular and linear motion information.
