Product Descripion
Micro Gyroscope Assembly is a compact sensing unit designed to measure two- or three-axis angular rates of a carrier. It integrates a high-performance MEMS gyroscope, temperature sensor, signal processing board, and embedded software.
The system provides accurate angular rate data through RS-422 output, featuring built-in error compensation for temperature drift, installation misalignment, and nonlinearity, ensuring high precision and stability.
With its small size, low power consumption, and high reliability, it is ideal for inertial navigation, attitude control, UAVs, robotics, and stabilization systems.
