The MSI300 MEMS Integrated Navigation System is a high-precision, high-reliability, and cost-effective MEMS inertial navigation system designed for navigation, control, and measurement applications in vehicles, ships, drones, and other similar platforms.
The MSI300 series integrated navigation system integrates high-performance MEMS gyroscopes, MEMS accelerometers, and GNSS satellite receiver chips internally. By sensing the Earth's angular velocity and acceleration, it statically self-aligns to determine the true heading of the carrier's motion. This is then fused with the three-dimensional velocity, position, and heading data obtained from the GNSS receiver to achieve integrated navigation. The integrated navigation system has undergone full-temperature zero-point and full-temperature scale compensation for its internal IMU modules, ensuring the reliability of the product.
Liocrebif Company is a high-tech enterprise that has achieved a fully closed-loop system for fiber optic winding equipment, fiber optic winding manufacturing, IMU circuits, software, and IMU testing and calibration equipment. By comprehensively controlling upstream and downstream processes, the company can effectively improve product quality and reduce system costs. The company implements the ISO9001 quality system and adopts strict processes to ensure the reliability and consistency of product performance.
The products offer various configuration options to accommodate different platforms, such as airborne, vehicle-mounted, and ship-mounted applications. When vehicle-mounted, the system incorporates vehicle constraints to ensure long-term measurement accuracy of attitude.
