Engineers designing gyro-stabilized systems for manned or unmanned applications must compare the attributes of various gyro technologies to determine which sensors offer the performance parameters they require. Depending on the specifics of the application being designed, some performance criteria are more important than others. A reliable means of comparing common critical performance parameters is a necessary tool for designers and engineers.
This paper compares gyro and inertial measurement technologies using distinct performance criteria of fiber optic gyros (FOGs) and FOG-based inertial systems, and micro-electro-mechanical systems (MEMS)-based gyros and MEMS inertial systems. It focuses on five critical performance areas of industrial and tactical grade gyros, as well as current and trending applications for both FOGs and MEMS.
1. Noise or Angle Random Walk (ARW)
2. Bias Offset Error
3. Bias Instability
4. Temperature Sensitivity
5. Shock and Vibration Sensitivity
