Used By: This entry is used directly by one other data structure in this standard, a MSG called
MSG_RoadSideAlert <ASN> <XML>. In addition, this item may be used by data structures in other
ITS standards.
Remarks: Some message sets allow a request of other relevant messages by use of this ID, some others do
not. Some messages do not yet support this ID and force the message receiver to sort the recovered
message to align event geographically. This is expected to be an area of harmonization. Developers should
also note that data from different source agencies can vary with the numbering used as well.
7.50 Data Element: DE_GPSstatus
Use: The DE_GPSstatus data element is used to relate the current stae of a GPS systems in terms of its
general health, lock on satellites in view, and use of any correction information. Various bits can be
asserted to reflect these values.
