This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
Used By: This entry is directly used by the following 3 other data structures in this standard (record type,
descriptive name, ASN.1, and XML name (if present) of each):
DF
<XML>, and
DF
<XML>, and
DF
In addition, this item may be used by data structures in other ITS standards.
6.45 Data Frame: DF_UpdateVector
Use: A minimal report of the vehicles position, speed, and heading. Used in the probe vehicle message as
one of the subsequent reports of position information (preceded by a longer frame with additional
information which does not vary).
ASN.1 Representation:
UpdateVector ::= SEQUENCE {
lastMin DMinute, -- 1 byte
lastSec DSecond, -- 2 bytes
long Longitude, -- 4 bytes, 1/8th microdegree
lat Latitude, -- 4 bytes, 1/8th microdegree
heading Heading, -- 1 byte, 1.4 deg
speed Speed, -- 1 byte
elevation Elevation, -- 3 byte
... -- # LOCAL_CONTENT
} -- a size of 16 bytes

6.46 Data Frame: DF_ValidRegion
Use: The ValidRegion DF is used to describe one or more geographic locations to which a message
(typically road signs or advisories of some sort) is applied or considered valid.
ASN.1 Representation:
ValidRegion ::= SEQUENCE {
