Glossary

GMT

(Greenwich Mean Time)

Central European time

Standard time at degree of longitude 0

(the degree of longitude through Green-

wich, Great Britain). This time is used all

over the world as the standard time for

synchronising data acquisition.

GPS

(Global Positioning System)

GPS uses satellites to calculate your cur-

rent geographical position. It is based on a

total of 24 satellites orbiting the Earth and

emitting signals. A GPS receiver receives

these signals and uses the signal time dif-

ferences to calculate the distance to an in-

dividual satellite and thus the current geo-

graphical position (longitude and

latitude). Signals from at least three satel-

lites are required for positioning. The cur-

rent height can also be calculated if signals

are received from four or more satellites.

PTT

(Push To Talk)

For this unit it means that after a selection

of PTT a address can be spoken. The

address is then processed by the navigati-

on system.

SD card

(Secure Digital)

The SD card was developed in 2001 by

SanDisk and is based on the older MMC

standard. An SD card is a rewriteable re-

movable memory card.

TMC

(Traffic Message Channel)

Traffic announcements transmitted by

most FM stations via RDS. Basis for dy-

namic navigation.

TMCpro

(Traffic Message Channel Professional)

A free TMC traffic alert service which is

broadcast in Germany on various private

channels. The messages of this service are

more precise than standard traffic messag-

es. The service is offered since April 2004.

The license fees are already paid with the

price of the TMCpro-enabled navigation

system.

USB

(Universal Serial Bus)

The Universal Serial Bus (USB) is a bus

system for connecting a computer to ex-

ternal USB peripherals for exchanging da-

ta.

There are two different standards with

various transmission speeds. USB 1.1

transfers at a speed of 12 Mbit/s and USB

2.0 transfers at 480 Mbit/s.

For a transfer of large amounts of data de-

vices that use the USB 2.0 standard

should be used.
