Compact Structure & Wide Application
The MEMS INS/GNSS MNAV-H01 Series MEMS Inertial/Satellite Integrated Navigation System is a highly reliable, cost-effective 6-axis navigation product, ideal for navigation, control, and measurement in missile-borne platforms, high-dynamic UAVs, unmanned ground vehicles, and unmanned surface vessels.
It integrates high-precision 3-axis MEMS gyroscopes, 3-axis MEMS accelerometers, a dual-antenna GNSS receiver, signal processing circuits, and navigation software, delivering complete navigation and attitude calculation capabilities.
Advanced Manufacturing Processes & Technology
Leveraging leading MEMS processes, the system integrates inertial components with performance comparable to low-precision fiber-optic gyroscopes. Full-temperature parameter compensation (for zero bias, scale factor, non-orthogonal error, etc.) ensures sustained high measurement accuracy over time. An built-in adaptive attitude algorithm guarantees long-term stability in 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.
