On GPS
GPS (Global Positioning System) satellites
continuously emit signals for positioning
anywhere on the earth. As a GPS aerial receives
these signals, users can be informed of their
location (latitude, longitude and altitude).
Information must be received from 3 satellites in
order to obtain two-dimensional fixes (altitude
and longitude), and 4 satellites are required for
three-dimensional positioning (latitude,
longitude and altitude). As GPS satellites are
controlled by the U.S. Department of Defense, a
deliberate margin of error between a few metres
(a few feet) and 10 metres (32.8 feet) exists. As a
result, the GPS navigation system may include
an error of between 10 metres (32.8 feet) and
about 200 metres (656.2 feet), depending on the
circumstances.
As GPS information is obtained using signal
from satellites, it may be impossible or difficult
to obtain the information in the following
locations:
• Tunnel or underground
• Under a highway
• Between high buildings
• Between tall trees with dense foliage
Note
When the reverse signal and the speed sensor cords
are connected, the system calculates the current car
position with detecting the direction and the travel
distance of the car by the gyroscope and speed pulse
respectively even in locations where the GPS signal
cannot be received.
