Figure 7.3.6b-1: Shape description of a High Accuracy Ellipsoid point with altitude and uncertainty ellipsoid

High Accuracy Degrees of Latitude:

Bit 8 of octet 2 is the high order bit.

Bit 1 of octet 5 is the low order bit.

High Accuracy Degrees of Longitude:

Bit 8 of octet 6 is the high order bit.

Bit 1 of octet 9 is the low order bit.

High Accuracy Altitude:

Bit 6 of octet 10 is the high order bit.

Bit 1 of octet 12 is the low order bit.

Orientation of major axis:

angle in degrees between the major axis and north

(0 = north, 90 = east, values of 180 and above are not used).

HU: Horizontal Uncertainty Range

Bit value 0 High Accuracy default uncertainty range used.

Bit value 1 High Accuracy Extended Uncertainty Range used.

VU: Vertical Uncertainty Range

Bit value 0 High Accuracy default uncertainty range used.

Bit value 1 High Accuracy Extended Uncertainty Range used.

NOTE: Horizontal and vertical accuracy are coded as specified by "High Accuracy Uncertainty" (defined in clause 6.2a) or "High Accuracy Extended Uncertainty" (defined in clause 6.2b). Different coding can be used for horizontal and vertical location components.
