Inertial Navigation/GNSS Integrated Navigation System

MS20062

High-Precision North Finding Based on MEMS Technology

The MS20062 MEMS Integrated Navigation System is a highly reliable, cost-effective inertial navigation solution, widely used for navigation, control, and measurement in vehicles, vessels, UAVs, and other platforms.It integrates high-performance MEMS gyroscopes, accelerometers, and a GNSS chip to calculate heading, 3D velocity, position, and attitude in real time. Built-in full-temperature compensation ensures reliability, with configurable operating modes for airborne, land, and marine applications.

Advanced Manufacturing Processes & Technology

Leveraging leading MEMS processes, it integrates inertial components with performance comparable to low-precision fiber-optic gyroscopes. Full-temperature parameter compensation maintains high accuracy, and an adaptive navigation algorithm ensures stable long-term attitude measurements.

Core Self-Aligning Technology

Equipped with high-performance gyroscopes, the system achieves initial north finding without dual-antenna assistance, enabling fast convergence and sustained high accuracy during dynamic navigation.
