Specialist words Active Sync
Active Sync is a Microsoft product. This is
the standard synchronisation software for
Windows mobile units such as your Traf-
fic Assist. The programme can be down-
loaded free-of-charge from the internet.
GMT
(Greenwich Mean Time)
Central European Time
The standard time at 0 degrees of longi-
tude (the longitude which passes through
Greenwich, Great Britain). This time is
used worldwide for the synchronisation of
data collection.
GPS
(Global Positioning System)
GPS determines your actual geographical
position by the use of satellites. It is based
on 24 satellites which orbit the Earth and
emit signals. The GPS receiver receives
these signals and calculates the distance to
each satellite from the running time dif-
ferences and thus evaluates its actual cur-
rent position in terms of geographical
length and width. In order to determine
the position, signals from at least three sat-
ellites are required, and the fourth one al-
lows the height to be determined.
HDOP
(Horizontal Dilution Of Precision)
HDOP states the quality of the positional
dtermination. In theory, values from 0 to
50 are possible, whereby the following ap-
plies: the smaller the value the more accu-
rate the positioning (value 0= no deviation
from the actual position). Values of up to
8 are acceptable for navigation units.
ID3-Tag
„Index of Contents" of an MP3 title.
Contains information such as title, artist,
album, year and genre.
JPG/JPEG
(Joint Photographic Experts Group)
The JPEG is the most common type
of storage format for dissipating picture
compression., i.e. when compressing, de-
tails of the picture are lost. Still provides
good picture quality despite compression,
compression stages are selectable. It is the
most common format for representation
and exchange of pictures on the internet.
Memory Card
A re-writable storage card. In the Traffic
Assist it is a SD card.
MP3
Special compression process for audio
data (e.g. music).
