MG3-1A MEMS Gyroscope is a precision 3-axis angular rate sensor for UAV navigation, autonomous systems, and robotic stabilization.
It integrates MEMS gyroscope, temperature sensor, signal processing board, structure, and software for error-compensated angular rate output via RS-422.
Key features include ±400°/s measuring range, zero-bias instability 0.3°/h, random walk 0.15°/√h, bandwidth 250 Hz, and start-up 17 s. Compact (52 g), ideal for drone gyroscopes, robotic platforms, motion control, and mapping instruments.
Fully compatible with Stim210, it is a drop-in replacement for high-precision INS and attitude measurement systems.
