High Performance Inertial Navigation System Designed for Inertial Grade Navigation Accuracy

LKF-FN100 is a high-performance fiber-optic inertial navigation system, which can achieve high-precision alignment without any auxiliary information and provide inertial grade position, speed and attitude information. And the IMU includes three-axis fiber optic gyroscope (FOG) and three orthogonal quartz flexible accelerometers, which provides an inertial-grade solution. The three-axis fiber optic gyroscope is used to sense the angular motion of the carrier and outputs digital signals proportional to the angular velocity of the carrier. And the three orthogonal quartz flexible accelerometers are used to the linear acceleration of the carrier. Compared with other INS, the FOG inertial navigation system has significant long-life and high reliability advantages.

Designed for Flexibility and Integration

LKF-FN100 contains a variety of navigation modes, which can be adapted to underwater, vehicle, airborne and other different environments. In the marine applications, LKF-FN100 can be easily operated in the compass mode, which can still be autonomous alignment and navigation in the absence of any external information assistance. At the same time, LKF-FN100 can be integrated with Global Navigation Satellite System (GNSS), Doppler Velocity Log (DVL) and Odometer (ODO) to form an integrated navigation system, which combines two different but complementary navigation modes. The integrated navigation system uses the optimal estimation method and is able to provide stable and continuous high frequency navigation information, which is an inertial grade solution. LKF-FN100 can form RTK real-time differential system with satellite reference station, which can support post-processing and provide angular-second attitude reference and centimeter-level position accuracy. LKF-FN100 can also be used in the sea to provide measurement information of three axis wave (heave).
