Attitude and Heading Reference System (AHRS)


An Attitude and Heading Reference System (AHRS) is a three-axis sensor system that provides real-time three-dimensional attitude positions and heading. AHRSs use solid-state or Micro-Electromechanical Systems (MEMSs), gyroscopes, accelerometers, magnetometers, and a built-in digital signal processor to obtain attitude and heading reference information. These sensors, in combination with a built-in digital signal processor, create an inertial sensor system capable of measuring the attitude of objects in 3D space.

Market Scenario of AHRS

The attitude and heading reference systems market is projected to grow from USD 537.5 million in 2016 to USD 723.8 million by 2022, at a CAGR of 5.08% from 2016 to 2022. Rise in aircraft deliveries, owing to the increasing air passenger traffic across the globe, and increasing demand of attitude and heading reference systems for use in Unmanned Aerial Vehicles (UAVs) are the key factors driving the growth of the attitude and heading reference systems market.


  • Stabilized Platforms: Unmanned Aerial Vehicle (UAV) markets use inertial altitude and motion to point and steady digital cameras. Directional antennas on tripod, ship, or ground vehicle also utilize INS data to orientate turret control systems.
  • Aerial Systems: Inertial navigation systems are employed to identify aircraft orientation, relative angles to ground targets, altitude stabilization, and waypoint navigation.
  • Robotics: Robot agility is enhanced as feedback systems use inertial motion, attitude, velocity, and position in dynamic control. Autonomous robots must accurately navigate and interact with their environment both indoors and outdoors.
  • Intuitively control and interact with natural user interfaces and games in augmented reality, virtual reality, TV, PC and gaming systems. Create and enjoy immersive experiences and intuitive controls for 3D audio, augmented reality, virtual reality, and motion capture systems.
