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.
