SG102 AHRS Installation/Calibration Utility

3 Introduction
The SG102 AHRS Installation/Calibration Utility version 2.80 and higher is a Windows
application program which runs on a laptop or PC. When used in conjunction with the
SG102 Maintenance Adapter it uses the computer’s USB port to perform the mount
position selection and compass alignment of the SG102/MT102 system after installation
in the aircraft.
The software works with all versions of SG102. Where a specific step is version-specific,
this will be noted in the instructions.
For SG102 software version 1.26 or later, this utility performs a 2-step coarse-fine
calibration. This enhancement allows improved performance when operating in more
difficult (i.e. highly magnetized) airframe environments.
For SG102 Mod 2 or later hardware with software version 1.50 or later, this utility
presents the option for ARINC 429 High Speed.
The final system calibration values are stored in a configuration module physically
located in the MT102. This calibration data is retrieved every time the SG102 system
powers up. In the event of an SG102 replacement the calibration data stays with the
aircraft and therefore realignment of the SG102 is not required.
Note: The SG102 Maintenance Adapter Windows Drivers must be installed on
the PC first. See the Maintenance Adapter User Guide.
