These are sometimes referred to as MARG (Magnetic, Angular Rate, and Gravity) sensors and consist of either solid-state or microelectromechanical systems (MEMS) gyroscopes, accelerometers and magnetometers. They are designed to replace traditional mechanical gyroscopic flight instruments. -==== - [More Info]https://en.wikipedia.org/wiki/Attitude_and_heading_reference_system[^] +==== - - -[[cheat-Articles]] === IMU image:./sensors_1604_LRG.jpg[alt="Adafruit 10-DOF IMU Breakout"]
