Slide 5: Key Gyro Performance Factors
Key Gyro Performance Factors Five critical areas where industrial/tactical grade gyros must outperform consumer grade gyros while maintaining small form factor and low cost • Noise or Angle Random Walk (ARW) – High frequency, mostly white-noise • Bias Offset Error – A stationary gyro can incorrectly
Slide 6: Key Gyro Performance Factors: Noise or Angle Random Walk
Key Gyro Performance Factors • Noise or Angle Random Walk (ARW) – The output of a gyro includes a broadband, random (white) noise element – Angle Random Walk (ARW) describes the average deviation or error that will occur as a result of this noise element – ARW can be obtained from the Allan Variance
