Attitude and Heading Reference Systems

Airborne-Qualified AHRS for Flight Instrumentation & Autonomous Platforms

Aeron's AHRS solution is delivered through the Octantis 2 AN5300S — a tactical-grade MEMS attitude and heading reference system qualified for airborne use as a primary or standby instrument across fighter, transport and passenger aircraft, and for autonomous control in unmanned platforms.

The Attitude & Heading Sensing Challenge

Flight instrumentation and autonomous platforms need continuous, trustworthy attitude and heading data — even under vibration, shock and thermal extremes — and the software driving it must meet the same certification bar as the airframe it flies on.

  • Flight-Critical Reliability

    Attitude and heading data must stay accurate through the full dynamic envelope of fighter, transport and UAV operation.

  • Certification Burden

    Airborne deployment demands DO-178B software assurance, MIL-STD hardware qualification and airworthiness certification.

  • Independent Operation

    The system must function as a standalone reference, with external aiding as an enhancement — not a dependency.

Aeron's Approach: One Certified AHRS Core

The solution is built around the Octantis 2 AN5300S — tactical-grade MEMS gyroscopes, accelerometers and a built-in magnetometer, fused through Aeron's proprietary multi-modal Extended Kalman Filter engine to deliver uninterrupted, high-performance attitude and heading data.

The same certified core can serve as a primary or standby instrument for electronic flight instrumentation and cockpit displays across fighter, transport and passenger aircraft, or drive autonomous control loops in unmanned aerial vehicles — without changing the underlying qualification or software baseline.

What the Solution Delivers

  • Extended Kalman filter estimation engine
  • Redundant triaxial solid-state MEMS accelerometers & gyroscopes
  • External True Airspeed (TAS) aiding
  • External magnetometer input
  • High dynamic range up to ±450°/s and ±15g
  • Functional shock sustainance 20g

How the Solution Works

Sensor inputs are fused in real time through a multi-modal Extended Kalman Filter to deliver stable attitude and heading estimates.
