Introduction
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.
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.
