How It Works: Attitude and Heading Reference System

Gemini Sparkle

Key Takeaways:

  • Attitude and Heading Reference Systems (AHRS) provide highly accurate heading and attitude information using solid-state technology, surpassing traditional mechanical gyros.
  • AHRS operates by integrating data from micro-electronic mechanical gyros (capturing motion), accelerometers (providing attitude reference and correcting gyro drift using gravity), and magnetometers or flux valves (supplying heading information using Earth's magnetic field).
  • The system aggregates this information and performs complex algorithms to deliver reliable data, becoming significantly smaller, lighter, and more affordable due to advancements in the automotive industry.

Attitude and heading reference systems (AHRS) have been providing heading and attitude information with greater accuracy and reliability than traditional mechanical gyros for years now. But how do these solid-state systems deliver this information, and how do they do so using increasingly smaller and lighter equipment?
