Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_Approach <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
6.8 Data Frame: DF_BreadCrumbVersion-1
Use: The BreadCrumbVersion-1 data frame 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). In this data frame
each element is delimited by tags, in other variants the data is expressed in a single octet blob.
ASN.1 Representation:
BreadCrumbVersion-1 ::= SEQUENCE {
longOffset INTEGER (-32767..32767),
-- where the LSB is in
-- units of 1/8th micro degree
-- max delta vaue 4095 mDeg (about ~1500 ft)
-- 2 bytes in length
latOffset INTEGER (-32767..32767),
-- where the LSB is in
-- units of 1/8th micro degree
-- 2 bytes in length
zOffset INTEGER (-127..127) OPTIONAL,
-- where the LSB is in
-- units of 20 cm
-- max delta value is about 25.4 meters
-- 1 byte in length
time INTEGER (1..32758) OPTIONAL,
-- where the LSB is in
-- units of 0.1 milliSeconds
-- max delta value about 54.6 minutes
-- 2 bytes in length
accuracy PositionalAccuracy OPTIONAL,
