FOG Based IMU

The inertial measurement unit (hereinafter referred to as "the product") utilizes a three-axis integrated fiber optic gyroscope and a three-axis quartz accelerometer as the sensing devices for angular velocity and apparent acceleration, respectively, to measure the angular velocity and acceleration information of each axis in the carrier coordinate system. The angular velocity and acceleration information are sent to the acquisition and processing circuit, where they undergo sampling, filtering, and error compensation before being output externally as angular velocity and apparent acceleration information.

UF300 series is the most cost-effective fiber optic inertial measurement unit with medium to high precision, which can be used for navigation, control, and dynamic measurement. The system adopts a highly reliable three-axis integrated closed-loop fiber optic gyroscope, with comprehensive performance exceeding the imported KVH1750.
