Product Description

High-Precision MEMS 3 Axis Gyroscope with 0.3°/s Bias Instability for Navigation System

The MG3-1A MEMS Gyroscope is designed for high-precision inertial navigation, robotic stabilization, and UAV guidance. This advanced system integrates a 3-axis MEMS gyroscope, temperature sensor, signal processing board, structure, and specialized software, delivering two/three axis angular rate measurements with full error compensation (temperature, misalignment, and nonlinearity).

The sensor outputs data via RS-422 with a measuring range of ±400°/s, zero-bias instability of 0.3 °/h, and high resolution of 2 °/h. With a start-up time of 17 seconds and weight of 52±5 g, it's ideal for compact UAVs, robotic arms, and autonomous survey platforms.

Fully compatible with Stim210, the MG3-1A ensures precision attitude measurement and navigation performance in harsh environments (-45~85°C), making it suitable for civil, industrial, and scientific applications.
