Product catalog summary
Overview
ASC's precision navigation and pointing gyroscopes utilize robust silicon MEMS vibrating ring elements to detect angular velocity through the Coriolis force effect. These gyroscopes are designed for industrial environments, offering excellent shock and vibration rejection.

Product Variants
Two main models are available: ASC 271 (Uniaxial) and ASC 273 (Triaxial). Both models feature anodised aluminium housing for lightweight and case isolation against ground loops.

Key Features
  • Rate ranges: ±75°/s, ±150°/s, ±300°/s, and ±900°/s
  • Low bias instability (9°/hr) and low angular random walk (0.2°/√hr)
  • Low power consumption and high shock rejection
  • Wide bandwidth and low g-sensitivity

Applications
  • Precision navigation and pointing
  • Automotive in-car navigation
  • Precision GPS vehicle and personal navigation aiding
  • Vehicle yaw, pitch, and roll rate sensing
  • Gesture sensing and motion tracking
  • Precision agriculture and industrial robotics

Specifications
  • Dynamic rate range: 75, 150, 300, 900 ±°/s
  • Sensitivity: ±1% mV/°/s
  • Bandwidth: Max 150 Hz
  • Shock limit: 500 g (1 ms half-sine); 10000 g (survival)
  • Operating temperature range: -40°C to +85°C
  • Sealing: ASC 271 - IP65; ASC 273 - IP67

Electrical and Environmental Details
  • Excitation voltage: 7 to 40 V DC
  • Current consumption: ASC 271 - 6 mA per axis; ASC 273 - 18 mA for all axes
  • Bias: 1.65 ± 0.006 V
  • Bias variation with temperature: ±3 °/s
  • Case material: Anodised Aluminium
  • Weight: ASC 271 - 10g; ASC 273 - 35g

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).
