The Axitude AX1-[  ]  is a high performance, solid-state  attitude  and  heading  reference system  intended  for  General  Aviation applications, such as advanced flight displays and autopilots.  The Axitude AX1-[  ] provides accuracy and usability that comply with the demands of the relevant EASA ETSO standards.  In  more  details  the  system  has  been designed  to comply with  the demands of  the Federal  Aviation  Authority's  (FAA)  and  the European  Aviation  Safety  Agency  (EASA) high  standards  of  safety  and  reliability, including  an  extensive  built  in  test  (BIT) capability.  This  means  that  the  strap-down inertial  subsystem  provides  attitude  and heading  measurements  with  static  and dynamic  accuracy  that  exceeds  traditional spinning  mass  vertical  and  directional gyros. Further,  the  system  provides  an  accurate inertial  reference  in  avionics  dynamic environments  that  include  altitude, temperature,  shock  and  vibration  ranges according  to  the  guidelines  in  DO-160D "Environmental  Conditions  and  Test Procedures for Airborne Equipment". The  Axitude  AX1-[  ]  provides  the  following basic features:

• Attitude, angular rate and acceleration components

• High relative and absolute accuracies (superior to vertical and directional gyros).

• Acceptable real-time response in highly dynamic environments

• Unaffected by environment

• Integrity monitoring (BIT)

• High reliability

• Compatibility with avionics suite requirements

• Price affordability for the GA market

The Axitude AX1-[ ]  implements its features by employing proprietary extended Kalman Filter algorithms to determine stabilized roll, pitch,  and  heading  angles  in  static  and dynamic  conditions.  The  Kalman  Filter implementation results in a continuous on-line gyro bias calibration, and an adaptive attitude and  heading measurement  that  is  stabilized by  the  long  term gravity  and magnetic  north references. Output  data  is  provided  through  a  RS232 digital  format  interface.  Future  versions  will also provide a choice of standard avionic bus interfaces. Each  inertial  system  comes  with  both  an Installation  and  User’s  Manuals  offering helpful  hints  on  installation  and  product information.  In  addition,  Axitude  provides  a comprehensive suite of software to assist you in  installation,  system  evaluation  and  allows you to perform data acquisition.
