Small Size TDFG99IMU Fiber Optic Inertial Unit High Accuracy Light Weight

♦ Overview

This fiber optic inertial unit offers a compact, lightweight design with low power consumption and high precision. It features eight-point vibration damping, enabling reliable performance in high-impact and high-vibration environments. Suitable for pure strapdown applications, it meets the requirements of next-generation unmanned platforms, underwater/torpedo systems, as well as land, airborne, and missile weapon platforms that demand miniaturized yet high-precision inertial technology. Additionally, it provides dynamic measurement capabilities for both angular and linear motion of the carrier.
