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.
