6 Degrees of Freedom (6DOF)
Acceleration: Ax, Ay, Az
Rotation: p, q, r
Summary:
  • Provides extended Kalman filtered attitude and heading estimate
  • Integrated unit, no external computation device required
  • No drift
  • Easy integration via Ethernet and other protocols
  • Analog filtering for high-vibration environments
  • Open-source development tools (GCC and others)
  • Aluminum enclosure
  • Low-power: 2.5W to 3W
Applications:
  • Navigation Systems (aerial, ground, marine, submarine)
  • Flight Controllers
  • Complex attitude estimations
  • Virtual Reality
  • Augmented Reality
This is an attitude and heading reference system (AHRS). This is a self-contained unit that outputs the attitude of the system via a UDP ethernet protocol or optionally, the console serial port. The system incorporates a low-powered CPU that runs an extended Kalman filter

Features:

  • 3 gyroscopes
  • 3 accelerometers
  • 3 magnetometers
  • integrated XScale based computer (running GNU/linux OS)
  • Console serial port
  • 10/100 Ethernet interface
  • Compact flash expansion port
  • Compatible with autopilot.sf.net
