The gyro detects the magnitude and direction of angular velocity by using the coriolis force effect. As the gyro is rotated, coriolis forces acting on the silicon ring cause radial movement at the ring perimeter, the magnitude of which is proportional to the angular velocity of rotation. The gyro thus produces an analog voltage signal, which is linearly proportional to angular rate. The balanced ring design results in excellent shock and vibration insensitivity. Description ASC's precision navigation and pointing gyros are used typically in industrial environments due to their excellent shock and vibration rejection. ASC's gyroscopes, 271 and 273, feature an anodised aluminium housing, which is light-weight and provides case isolation against ground loops. The sensor sensitivity and bias is extremely stable over a wide temperature range from -40°C to +85°C. ASC's precision navigation and pointing gyros are available in two versions: 271 (Uniaxial) and 273 (Triaxial).
