Fog INS and GNSS integration

This product has built-in three-axis integrated high-precision fiber optic gyroscope, three-axis high-precision quartz flexible accelerometer and mobile surveying-level multi-mode multi-frequency GNSS receiver supporting autonomous Beidou function. Through advanced intelligent combined navigation algorithm and Kalman filter, it is optimized for GNSS occlusion and multipath interference, and can achieve high-precision heading, attitude, speed and position measurement of moving carriers. This inertial navigation system also has multiple sensor interfaces such as GNSS/odometer/DVL/barometric altimeter, which can well meet the long-term, high-precision and high-reliability navigation application requirements in complex environments such as urban canyons, and can be used for navigation and control of various unmanned systems. Product features include: fast and accurate determination of initial heading and attitude, support for real-time heading and attitude output, built-in GPS and Beidou dual-mode receiver, support for dynamic fast alignment, INS/GNSS combination integrated design, support for IE post-processing, enhanced Kalman filter algorithm, and resistance to electromagnetic interference and vibration. It can be used in vehicle-mounted, airborne, ship navigation, stability control and other fields.

IF3700 adopts a high-precision closed-loop fiber optic gyroscope with a full temperature of 0.01°/h and a 20 μg high-precision quartz accelerometer, which can achieve high-precision pure inertial orientation measurement. It has autonomous compass function and can maintain attitude and heading accuracy for a long time without external assistance. It can be used as the main navigation equipment for large unmanned aerial vehicles, unmanned ships, and unmanned submarines, and is widely used in related fields such as aviation, aerospace, and navigation.
