DistError:
For a magnetic calibration, this score indicates if the distribution of sample points is
sufficient, with an emphasis on the heading distribution. The score should be 0.
Significant clumping or a lack of sample points in a particular section can result in a
poor score. In the event of an aborted calibration the score will be 179.8
d
, or in the
event of an accel-only calibration the score will be 99.99
d
.
TiltError:
This score indicates if the SeaTRAX experienced sufficient tilt during a magnetic
calibration, taking into account the calibration method. The score should be 0. In the
event of an aborted calibration the score will be 179.8
d
, or in the event of an accel-
only calibration the score will be 99.99
d
.
TiltRange:
For a magnetic calibration, this reports the larger of either half the full-pitch range or
half the full-roll range of sample points. For example, if the device is pitched +10° to
-20º, and rolled +25º to -15º, the TiltRange value would be 20º, which represents half
the roll range. For Full-Range Calibration and Hard-Iron-Only Calibration, this
should be ≥45°. For 2D Calibration, ideally this should be ~2°. For Limited Tilt
Range Calibration the value should be as large a possible given the user’s constraints.
In the event of an aborted calibration the score will be 179.8
d
, or in the event of an
accel-only calibration the score will be 99.99

7.3.19 kSetConfigDone (frame ID 19
d
)
This frame is the response to kSetConfig frame. The frame has no payload.
7.3.20 kSetFIRFiltersDone (frame ID 20
d
)
This frame is the response to kSetFIRFilters. The frame has no payload.
7.3.21 kStartContinuousMode (frame ID 21
d
)
If the SeaTRAX is configured to operate in Continuous Acquisition Mode, as defined by
kSetAcqParams, then this frame initiates the outputting of data at a relatively fixed data
rate, where the data rate is established by the SampleDelay parameter. The frame has no
payload. The response is kGetDataResp.
7.3.22 kStopContinuousMode (frame ID 22
d
)
This frame commands the SeaTRAX to stop data output when in Continuous Acquisition
Mode. The frame has no payload.
