Inertial navigation combined with GNSS in a Fog sensor

The IF2700 fiber optic inertial navigation system is a small fiber optic combination inertial navigation system composed of a three-axis integrated fiber optic inertial IMU and satellite navigation system. It is used to measure the position, velocity, and attitude of the carrier in three directions, while outputting the angular velocity and acceleration of the three axes. Fiber optic inertial navigation includes a three-axis integrated fiber optic gyroscope and a three-axis integrated MEMS accelerometer. The accelerometer is sensitive to and measures the three-axis acceleration signal of the carrier, while the gyroscope is sensitive to and measures the three-axis angular velocity signal of the carrier. After compensation and calculation, the position, velocity, and attitude of the carrier are obtained; At the same time, Kalman filtering is used to effectively integrate INS and GNSS information, obtaining optimal estimates of position, velocity, and attitude, and improving the reliability and stability of fiber optic inertial navigation.

This product is equipped with a high-precision closed-loop fiber optic gyroscope with a full temperature of 0.001 °/h and a 10ug high-precision quartz accelerometer. It uses multi-sensor data fusion technology to combine inertial measurement with GNSS, enabling long-term high-precision integrated navigation.  The product also has post-processing function, which can be used to improve the heading, attitude, and position accuracy of the product through post-processing software.
