IG Device Integration Manual

5. IG-500E specific settings and behaviors with IG-Devices

When you configure the IG-500E to accept aiding data from an IG-Device, some specific settings, 
only related to IG-Devices, become available.

For more details, please have a look at the Appendix: Low level commands definitions.

5.1. Magnetometers management

When the remote magnetometers are used as a heading source, all internal magnetometer outputs 
are replaced by remote magnetometer outputs.

This behavior affects all outputs linked to the magnetometers:

Magnetometers Raw Data (if the remote device does not output magnetometers Raw data, 
this output is set to 0).

Calibrated magnetometer values

Mag Calib. Data. : These data are used for magnetometers calibration.

Therefore, when you run a hard and soft iron calibration, the result stored in the IG-500E 
corresponds to the remote magnetometer calibration.

Note: 

When the magnetic source is changed, the magnetic calibration present in IG-500E 

memory becomes inconsistent with the actual magnetometer used and must be performed again 
for proper operation.

5.2. GPS altitude reference

The IG-Device integration does not allow you to configure directly the GPS altitude reference 
(height above ellipsoid or above mean sea level). Instead of that, user should configure the remote 
IG-Device to output the desired altitude format.

5.3. IG-Device orientation offset

To work correctly, both the IG-500E and the attached IG-Device should use the same coordinate 
frame. 

When you know exactly the orientation offset between the IG-500E and the remote IG-Device, 
then, you should use this feature.
