SG102/D Digital Attitude Heading Reference System (AHRS)

​D, for Digital. The SG102/D Attitude Heading Reference System (AHRS) is identical to the SG102 (MOD2) without the analog interfaces. It’s lighter in weight and lighter in price. The SG102/D is designed for non-KG102 equipped aircraft and ideal for new equipment installs.

With an improved initialization time of one minute, it’s 3X faster than the original SG102. It also comes with a selectable low- and high-speed ARINC 429 output, which allows for additional interface options such as radar systems, satellite communication antennas and FLIR stabilization.

The SG102/D is available in three versions depending on the application



  • SG102/D-050: Fixed-Wing Piston Aircraft
  • SG102/D-150: Fixed-Wing Turbine Aircraft
  • SG102/D-250: High-Vibration Version for Helicopters
