What kind of gyro is utilized in the DGI?

The DGI (Dynamic Gyro Inertial) system typically utilizes fiber optic gyros (FOGs) or microelectromechanical systems (MEMS) gyros. Fiber optic gyros are known for their high precision and stability, making them suitable for applications requiring accurate angular rate measurements. In contrast, MEMS gyros are more compact and cost-effective, often used in consumer electronics and various automotive applications. The choice between them depends on the specific requirements of the application, such as accuracy, size, and cost.
