In addition, this item may be used by data structures in other ITS standards.
7.17 Data Element: DE_ElevationConfidence
Use: This DE is used to provide to listeners the confidence interval of the 95% confidence level for the currently
reported value of DE_Elevation, taking into account the current calibration and precision of the sensor(s) used to
measure and/or calculate the value. This data element is only to provide the listener with information on the
limitations of the sensing system; not to support any type of automatic error correction or to imply a guaranteed
maximum error. This data element should not be used for fault detection or diagnosis, but if a vehicle is able to
detect a fault, the confidence interval should be increased accordingly.
The frame of references and axis of rotation used shall be accordance with that defined in SAE J670, Issued 1976-
07 and its successors. Note the definitions provided in Figure 1 (Tire Axis System) and Figure 2 (Directional
Control Axis Systems).
