High performance fiber optic inertial measurement unit-OEM IMU75S
Product Description
This product has built-in high-precision three-axis integrated fiber-optic gyro, high-precision quartz flexure accelerometer and mobile mapping-grade multi-mode and multi-frequency GNSS receiver supporting autonomous BeiDou function. Through the advanced intelligent combination navigation algorithm and Kalman filter, optimized design for GNSS obstruction and multi-path interference, it can realize high-precision heading, attitude, speed and position measurement of moving carriers.
The inertial guidance system also has a variety of sensor interfaces such as GNSS/odometer/DVL/barometric altimeter, which can well meet the needs of long-time, high-precision and high-reliability navigation applications in complex environments such as urban canyons, and can be used for the navigation and control of all kinds of unmanned systems.
