MG3-1A MEMS Gyroscope provides accurate angular rate measurements for autonomous navigation, UAV systems, and robotic stabilization.
It features integrated temperature sensors, signal processing board, structural framework, and specialized software for full error-compensated output via RS-422, including temperature compensation, misalignment correction, and nonlinear adjustment.
Key performance parameters include ±400°/s measurement range, zero-bias stability of 3°/h, random walk of 0.15°/√h, and bandwidth of 250 Hz. Compact and lightweight (52 g), it is suitable for UAVs, autonomous vehicles, precision robotics, and mobile mapping instruments.
This Stim210 replacement ensures a drop-in solution for high-precision INS, attitude measurement, and motion control applications.
