In addition, this item may be used by data structures in other ITS standards.
6.23 Data Frame: DF_Position3D
Use: A collection of the two 4 byte lat-long information elements and the one 3 byte elevation used to build
a complete 3D position set in 11 bytes.
ASN.1 Representation:
Position3D ::= SEQUENCE {
lat Latitude, -- in 1/8th micro degrees
long Longitude, -- in 1/8th micro degrees
elevation Elevation
}
