### <a name="SemiAxisLength"></a>SemiAxisLength
This DE indicates the horizontal position confidence value which represents the estimated absolute position accuracy, in one of the axis direction as defined in a shape of ellipse with a
confidence level of 95 %.
The value shall be set to:
- `n (n > 0 and n < 4 094)` if the accuracy is equal to or less than n * 0,01 metre,

- `4 095` if the accuracy information is unavailable.
**Categories**: GeoReference Information
**Revision**: _Description revised in V2.1.1_
NOTE: The fact that a position coordinate value is received with confidence value set to 'unavailable(4095)'
can be caused by several reasons, such as:
- the sensor cannot deliver the accuracy at the defined confidence level because it is a low-end sensor,
- the sensor cannot calculate the accuracy due to lack of variables, or
- there has been a vehicle bus (e.g. CAN bus) error.
In all 3 cases above, the position coordinate value may be valid and used by the application.
If a position coordinate value is received and its confidence value is set to 'outOfRange(4094)', it means that
the position coordinate value is not valid and therefore cannot be trusted. Such value is not useful
for the application.

### <a name="SteeringWheelAngleConfidence"></a>SteeringWheelAngleConfidence
This DE indicates the steering wheel angle confidence value which represents the estimated absolute accuracy for a steering wheel angle value with a confidence level of 95 %.
- `n (n > 0 and n < 126)` if the confidence value is equal to or less than n x 1,5 degrees,
- `126` if the confidence value is out of range, i.e. greater than 187,5 degrees,
- `127` if the confidence value is not available.
If a steering wheel angle value is received and its confidence value is set to 'outOfRange(126)',
it means that the steering wheel angle value is not valid and therefore cannot be trusted.
Such value is not useful for the application.
**Categories**: Vehicle Information
**Revision**: _Description revised in V2.1.1_
>>>
NOTE: The fact that a steering wheel angle value is received with confidence value set to 'unavailable(127)'
can be caused by several reasons, such as:
- the sensor cannot deliver the accuracy at the defined confidence level because it is a low-end sensor,
- the sensor cannot calculate the accuracy due to lack of variables, or
- there has been a vehicle bus (e.g. CAN bus) error.
In all 3 cases above, the steering wheel angle value may be valid and used by the application.

- `-511` if the steering wheel angle is equal to or greater than 511 x 1,5 degrees = 766,5 degrees to the right,
- `n (n > -511 and n <= 0)` if the steering wheel angle is equal to or less than n x 1,5 degrees, and greater than (n-1) x 1,5 degrees,
- `n (n > 1 and n < 511)` if the steering wheel angle is equal to or less than n x 0,1 degrees, and greater than (n-1) x 0,1 degrees,
turning counter-clockwise (i.e. to the left),
- `511` if the steering wheel angle is greater than 510 x 1,5 degrees = 765 degrees to the left,

### <a name="TimestampIts"></a>TimestampIts
This DE represents the number of elapsed (TAI) milliseconds since the ITS Epoch.
The ITS epoch is `00:00:00.000 UTC, 1 January 2004`.
"Elapsed" means that the true number of milliseconds is continuously counted without interruption,
i.e. it is not altered by leap seconds, which occur in UTC.
EXAMPLE: The value for TimestampIts for 1 January 2007 00:00:00.000 UTC is `94 694 401 000` milliseconds,
which includes one leap second insertion since the ITS epoch.

NOTE: International Atomic Time (TAI) is the time reference coordinate on the basis of the readings of atomic clocks,
operated in accordance with the definition of the second, the unit of time of the International System of Units.
TAI is a continuous time scale. UTC has discontinuities, as it is occasionally adjusted by leap seconds.
As of 1 January, 2022, TimestampIts is 5 seconds ahead of UTC, because since the ITS epoch on 1 January 2004 00:00:00.000 UTC,
further 5 leap seconds have been inserted in UTC.
