ASC281 MEMS Gyroscope

Product Description

ASC’s uniaxial tactical grade gyroscope ASC 281 can be powered by a DC power supply (+6V to +30V) where the output voltage is independent of the supply. The excellent long-term bias and scale factor repeatability with low noise allows accurate operation of the angular rate sensor. The MEMS vibrating ring gyroscopes are available with rate ranges of ±100°/s and ±200°/s. The gyroscope features also a very low bias instability of 0.12°/hr and an excellent angular random walk of 0.017°/√hr leading to a FOG-like performance. The gyroscope sensors are made of lightweight anodised aluminium housing and feature a 4-pin Comtronic connector and a detachable cable. ASC’s precision navigation and pointing gyros are available in two versions: 281 (uniaxial) and 283 (triaxial). ASC’s precision navigation and pointing gyroscopes are made of robust silicon MEMS vibrating ring elements. 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 analogue voltage signal, which is linearly proportional to angular rate. The balanced ring design results in excellent shock and vibration insensitivity.
