MG3-1A MEMS Gyroscope is a fully integrated 3-axis angular rate sensor designed for precision inertial navigation, UAV guidance, and robotic motion
control.
It consists of a 3-axis MEMS gyroscope, temperature sensor, signal processing board,
structural components, and dedicated software, delivering temperature-compensated, alignment-corrected, and
linearity-corrected angular rate data through RS-422.
With a measuring range of ±400°/s, zero-bias instability of 0.3°/h, random walk of 0.15°/√h, and start-up time of 17 s, the MG3-1A is perfect for UAVs, autonomous survey platforms, mobile robotics, and precision
navigation instruments.
As a Stim210 compatible replacement, it provides a compact (52 g), reliable, and high-precision solution for civilian and research INS applications.
