Aber zumindest die Frage, wo die GPS-Antenne sitzt, ist ganz klar beantwortet: im Armaturenbrett!
GPS
The signals received from GPS satellites are
extremely weak (less than a millionth of the
strength of a local FM station) and require
an unobstructed view of the sky. The GPS
antenna is located in the dashboard. The
signal reception can easily be interrupted or
interfered with by the following:
• Metallic window tint on the front or side
windows
• Cell phones, PDAs, or other electronic
devices docked in a cradle or lying loose
on the dashboard
• Remote starters or “hidden” vehicle
tracking systems mounted near the
navigation unit
• Audio electronic devices mounted near
the navigation unit
• Trees, tall buildings, freeway overpasses,
tunnels, or overhead electrical power
wires
GPS is operated by the U.S. Department of
Defense. For security reasons, there are
certain inaccuracies built into GPS for which
the navigation system must constantly
compensate. This can cause occasional
positioning errors of up to several hundred
feet.
