6.4.1 GPS Data Displayed
The virtual sky on the left
represents the currently visible
part of the sky above you, with
your position as the center.
The satellites are shown at
their current positions. The
GPS receives data from the
green and grey satellites but
not from the red ones. Signals
from the grey satellites are only
received, while green ones are
used by the GPS to calculate
your current location. On the
right you can see the satellite
signal strength bars. The more
satellites your GPS tracks (the
green ones), the better your
calculated position will be.
Additional pieces of information
on this screen are: current
position in latitude/longitude
format, elevation, speed, date,
time and calculated accuracy.
NOTE :
Accuracy can be affected by
several factors the GPS cannot
take into account. Use this
accuracy information only as
estimation.
There are two icons on the left
to show the status of the GPS
connection and the quality of
reception.
6.4.2 GPS Connection
Indicator
In the middle to the left there is
a lamp similar to the ones used
for switches. This one has more
colors and represents more
values:
A fast blinking green
lamp means that there
is communication with
the GPS and data is
being received.
Other colors should not appear
with a built-in GPS. Should any
of these appear, this means a
faulty operation of your device.
6.4.3 GPS Data Quality
Indicator
In the top left corner there is a
satellite dish to show the quality
of the GPS position. Different
colors represent different
signals:
Red shows there is
no connection with
the GPS device. This
should never be the
case if your device has
a built-in GPS.
