Low Drift Inertial Navigation System
,Fiber Optic GNSS INS System
,Marine Fiber Optic Inertial Navigation System
This product has built-in three-axis integrated high-precision 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.
This inertial navigation system 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 various unmanned systems.
