MG3-1A MEMS Gyroscope provides accurate and stable 3-axis angular rate measurements for UAVs, autonomous navigation systems, and robotic stabilization.
It includes a 3-axis MEMS gyroscope, temperature sensor, signal processing board, structural frame, and dedicated software with RS-422 output and full error compensation (temperature, misalignment, nonlinearity).
Technical specifications: ±400°/s range, zero-bias instability 0.3°/h, random walk 0.15°/√h, start-up 17 s, weight 52 g. Ideal for drone navigation, robotic motion control, mapping instruments, and autonomous vehicles.
As a Stim210 replacement, it delivers a drop-in high-performance MEMS gyroscope solution.
