Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_VehicleMotionTrail <ASN> <XML>. In addition, this item may be used by data structures in
other ITS standards.
Remarks: The delta units used in the latOffset and Long offset are 1/8th micro degrees from the
anchor point given by the full position vector. The delta units used in the zOffset are 0.1 meters
from the elevation of the full position vector. The delta units of time used in the time offset are
0.1 mSec. The delta units used in the heading are units of 002136 deg. The delta units used in
the speed are units of 0.05 m/Sec.
7.17 Data Element: DE_BreadCrumbVersion-6
Use: The BreadCrumbVersion-6 data element one of a set of related items to carry breadcrumb data
(typically vehicle trials). In use, sequences of this data set are sent (one per crumb), typically combined
into a single final octet string.
ASN.1 Representation:
BreadCrumbVersion-6 ::= OCTET STRING (SIZE(5))
