Enumeration Type Documentation

enum _SbgEComMagCalibBandwidth

Used to select the expected dynamics during the magnetic calibration.

Enumerator
SBG_ECOM_MAG_CALIB_LOW_BW	Tell the device that low dynamics will be observed during the magnetic calibration process.
SBG_ECOM_MAG_CALIB_MEDIUM_BW	Tell the device that normal dynamics will be observed during the magnetic calibration process.
SBG_ECOM_MAG_CALIB_HIGH_BW	Tell the device that high dynamics will be observed during the magnetic calibration process.

Definition at line 45 of file sbgEComCmdMag.h.

enum _SbgEComMagCalibConfidence

Confidence indicator on results of an onbard magnetic calibration.

Enumerator
SBG_ECOM_MAG_CALIB_TRUST_HIGH	Reported quality indicator can be trusted as enough remarkable magnetic field points have been acquired.
SBG_ECOM_MAG_CALIB_TRUST_MEDIUM	Few remarkable magnetic field points have been used to compute the magnetic calibration leading to a medium confidence in reported quality indicators.
SBG_ECOM_MAG_CALIB_TRUST_LOW	Even if the quality indicator could report an excellent calibration, The data set used to compute the magnetic calibration was not meaningful enough to compute meaningful quality indicators. This calibration should be used carefully.

Definition at line 66 of file sbgEComCmdMag.h.

enum _SbgEComMagCalibMode

Define if the onboard magnetic calibration should acquiere points for a 3D or 2D calibration.

Enumerator
SBG_ECOM_MAG_CALIB_MODE_2D	Tell the device that the magnetic calibration will be performed with limited motions. This calibration mode is only designed to be used when roll and pitch motions are less than � 5�. To work correctly, the device should be rotated through at least a full circle.
SBG_ECOM_MAG_CALIB_MODE_3D	Tell the device to start a full 3D magnetic calibration procedure. The 3D magnetic calibration offers the best accuracy but needs at least motion of � 30� on the roll and pitch angles.

Definition at line 32 of file sbgEComCmdMag.h.

enum _SbgEComMagCalibQuality

General quality indicator of an onboard magnetic calibration.

Enumerator
SBG_ECOM_MAG_CALIB_QUAL_OPTIMAL	All acquired points fit very well on a unit sphere after the calibration.
SBG_ECOM_MAG_CALIB_QUAL_GOOD	Small deviations of the magnetic field norm have been detected. The magnetic calibration should although provide accurate heading.
SBG_ECOM_MAG_CALIB_QUAL_POOR	Large deviations of the magnetic field norm have been detected. It may come from external magnetic distortions during the calibration.
SBG_ECOM_MAG_CALIB_QUAL_INVALID	No valid magnetic calibration has been computed. It could comes from too much magnetic disturbances, insufficient or invalid motions.

Definition at line 55 of file sbgEComCmdMag.h.

enum _SbgEComMagModelsStdIds

This enum defines the different magnetometer model IDs available in standard

Enumerator
SBG_ECOM_MAG_MODEL_NORMAL	Should be used in most applications
SBG_ECOM_MAG_MODEL_NOISY_MAG_TOLERANT	Should be used in disturbed magnetic environment
