Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_MovementState <ASN> <XML>. In addition, this item may be used by data structures in other
ITS standards.
7.101 Data Element: DE_PositionalAccuracy
Use: The DE_ Positional Accuracy element is a 4 byte octet of packed data consisting of various
parameters of quality used to model the accuracy of the positional determination with respect of a each
given axis. Note that because the 3 data elements are packed as one single data object, this is treated as a
data element not a data frame.
ASN.1 Representation:
PositionalAccuracy ::= OCTET STRING (SIZE(4))
-- And the bytes defined as folllows
-- Byte 1: semi-major accuracy at one standard dev
-- (signed range 0-12.7 meter. 0xFF=any value equal
-- or greater than 12.7 meter)
-- Byte 2: semi-minor accuracy at one standard dev
-- (signed range 0-12.7 meter. 0xFF=any value equal
-- or greater than 12.7 meter)
-- Bytes 3-4: orientation of semi-major axis
-- relative to true north (0-360 degree)
-- (In NMEA GPGST)
