Technical terminology

GMT

(Greenwich Mean Time)

Central European Time standard

Standard time at 0 degree longitude (the

longitude intersecting Greenwich, Great

Britain). This time is used worldwide for

synchronization of data collection.

Bluetooth

Technology for wireless data transmis-

sion at short range up to 10 metres.

GPS

(Global Positioning System)

GPS determines your actual geographi-

cal position by the use of satellites. It is

based on a total of 24 satellites which or-

bit the Earth and transmit signals. The

GPS receiver receives these signals and

calculates the distance to each satellite

from the running time differences and

thus evaluates its actual current position

in terms of geographical length and

width. In order to determine the position,

signals from at least three satellites are

required, and the fourth one allows the

height to be determined.

JPG/JPEG

(Joint Photographic Experts Group)

The JPEG is the most common type of

storage format for dissipating picture

compression., i.e. when compressing,

details of the picture are lost. Still pro-

vides good picture quality despite com-

pression, compression stages are se-

lectable. It is the most common format

for representation and exchange of pic-

tures on the internet.

SD card

(Secure Digital)

The Secure Digital Card was developed

in 2001 by SanDisk on the basis of the

older MMC standard. An SD card is a re-

writable change-over storage card.
