Introduction
The MSI100 MEMS Integrated Navigation System is a highly reliable, cost-effective MEMS inertial navigation system that can be widely used in navigation, control, and measurement applications in vehicles, ships, and drones.
The MSI100 series integrated navigation system integrates high-performance MEMS gyroscopes, MEMS accelerometers, and GNSS satellite receiver chips into its navigation calculation module. By measuring the angular velocity and acceleration of the carrier's motion, it continuously receives GNSS satellite signals via dual antennas or track angles, and calculates the current carrier's heading angle, three-dimensional velocity, position, and attitude information. The integrated navigation system has undergone full-temperature zero-point and full-temperature scale compensation for its internal IMU module, ensuring the reliability of the product.
Technical Specification
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. At the same time, 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.
