The mapping station application receives information
via a tetra fixed mobile radio. Location information
is sent from any vehicle fitted with a GPS receiver
via short data service messages over the infrastructure
control channel. The GPS information may be in
a number of pre-defined formats. These formats
are subsets from the GPGLL and other NMEA protocol
and contain selections from location, time, date
and speed etc.
