Product Description
The dual-axis gyroscope assembly offers superior performance with an angular rate measurement range of ±500°/s, zero-bias instability as low as 0.05°/h, and random walk of 0.02°/√h. All error compensation processes, including temperature and misalignment corrections, are carried out within the device, ensuring reliable output for attitude control and other precision applications.
With a weight of just 20g and an operating temperature range from -45°C to +85°C, this dual-axis gyroscope assembly combines high accuracy with a compact form factor. It is equipped with advanced error compensation algorithms, including zero-bias and temperature compensation, to ensure precise angular rate measurements even in demanding environments.
