MG3-1A MEMS Gyroscope is a high-precision 3-axis angular rate sensor for civil UAV navigation, robotic platforms, and autonomous motion control systems.
It integrates MEMS gyroscope technology, temperature sensors, signal processing board, structural components, and specialized software for full error-compensated angular rate measurements, output via RS-422.
Performance highlights include ±400°/s measuring range, zero-bias instability 0.3°/h, random walk 0.15°/√h, and bandwidth 250 Hz, making it suitable for UAVs, precision robotics, mapping instruments, and autonomous vehicles.
Fully compatible with Stim210, it provides a compact (52 g), reliable, drop-in solution for high-precision INS applications.
