specifying min, max and accuracy for related axes. Default unit of<br />
measure is degrees; can be overridden using explicit Unit and/or<br />
Unit Exponent.<br />
Heading X Axis SV – Indicates the compass X axis heading. Default unit of<br />
measure is degrees; can be overridden using explicit Unit and/or<br />
Unit Exponent.<br />
Heading Y Axis SV – Indicates the compass Y axis heading. Default unit of<br />
measure is degrees; can be overridden using explicit Unit and/or<br />
Unit Exponent.<br />
Heading Z Axis SV – Indicates the compass Z axis heading. Default unit of<br />
measure is degrees; can be overridden using explicit Unit and/or<br />
Unit Exponent.<br />
Heading Compensated<br />
Magnetic North<br />
Heading Compensated<br />
True North<br />
SV – Indicates compass magnetic heading has been compensated<br />
for tilt with respect to earth normal. Default unit of measure is<br />
degrees; can be overridden using explicit Unit and/or Unit<br />
Exponent.<br />
SV – Indicates compass true north heading has been compensated<br />
for tilt with respect to earth normal. Default unit of measure is<br />
degrees; can be overridden using explicit Unit and/or Unit<br />
Exponent.<br />
Heading Magnetic North SV – Indicates compass magnetic heading is not compensated.<br />
Default unit of measure is degrees; can be overridden using<br />
explicit Unit and/or Unit Exponent.<br />
Heading True North SV – Indicates compass true north heading is not compensated.<br />
Default unit of measure is degrees; can be overridden using<br />
explicit Unit and/or Unit Exponent.<br />
Distance SV – Indicates the distance magnitude without respect to which<br />
axis it occurs in. This is usually used as a composite value for<br />
specifying min, max and accuracy for related axes. Default unit of<br />
measure is meters; can be overridden using explicit Unit and/or<br />
Unit Exponent.<br />
Distance X Axis SV – Indicates the X axis distance. Default unit of measure is<br />
meters; can be overridden using explicit Unit and/or Unit<br />
Exponent.<br />
Distance Y Axis SV – Indicates the Y axis distance. Default unit of measure is<br />
meters; can be overridden using explicit Unit and/or Unit<br />
Exponent.<br />
Distance Z Axis SV – Indicates the Z axis distance. Default unit of measure is<br />
meters; can be overridden using explicit Unit and/or Unit<br />
Exponent.<br />
Distance Out-of-Range SF – TRUE when the sensor measuring distance indicates “out of<br />
range” meaning the value provided as Distance may not be<br />
accurate.<br />
Tilt SV – Indicates the inclinometer angle without respect to which<br />
axis it occurs in. This is usually used as a composite value for<br />
specifying min, max and accuracy for related axes. Default unit of<br />
measure is degrees; can be overridden using explicit Unit and/or<br />
Unit Exponent.
