Three Axis Angular Rate Sensor with High Shock Resistance for Motion Detection
The MG3-1A MEMS Gyroscope is a compact 3-axis angular rate sensor designed for autonomous navigation, UAVs, and robotics. This advanced sensor integrates MEMS gyroscope technology, temperature sensing, signal processing board, structural support, and software to deliver temperature-compensated, misalignment-corrected, and linearity-corrected RS-422 output.
