GPS
(Global Positioning System) GPS uses
satellites to calculate your current geo-
graphical position. It is based on a total of
24 satellites orbiting the Earth and emit-
ting signals. A GPS receiver receives these
signals and uses the signal time differences
to calculate the distance to an individual
satellite and thus the current geographical
position (longitude and latitude). Signals
from at least three satellites are required
for positioning. The current height can
also be calculated if signals are received
from four or more satellites.

USB
(Universal Serial Bus) The Universal Seri-

als for exchanging data.
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.
