Small Size Light Weight TDF61IMU0 Fiber Optic Inertial Unit Low Power Consumption
Fiber optic inertial units offer several advantages, including compact size, lightweight design, low power consumption, and high accuracy. They can be utilized to create pure strapdown, single-axis, and dual-axis modulation inertial units, effectively meeting the demands of new unmanned platforms, underwater or torpedo weapons, as well as land and airborne weapon systems that require compact and high-precision inertial equipment. Additionally, these units provide dynamic measurement capabilities for both angular and linear motion information of carriers.
