2025 Automotive MEMS 3-Axis Gyroscope for Vehicle Dynamics Control
The MG3-1A MEMS Gyroscope delivers precise angular rate measurements for autonomous navigation, UAV systems, and robotic stabilization applications.
This integrated solution features temperature sensors, signal processing board, structural framework, and specialized software for complete error-compensated output via RS-422, including:
- Temperature compensation
- Misalignment correction
- Nonlinear adjustment
Key performance specifications include ±400°/s measurement range, zero-bias stability of 3 °/h, random walk of 0.15 °/√h, and bandwidth of 250 Hz. With its compact design (52 g), it's ideal for UAVs, autonomous vehicles, precision robotics, and mobile mapping instruments.
As a Stim210 replacement, this gyroscope provides a drop-in solution for high-precision INS, attitude measurement, and motion control applications.
