To disable the A-GPS service, select Menu >
Applications > Location and Options >
Positioning settings > Positioning methods >
Assisted GPS > Disable .
You must have an internet access point defined in the
device to retrieve assistance data from the Nokia A-GPS
service over a packet data connection. The access point
for A-GPS can be defined in positioning settings. A
wireless LAN (WLAN) access point cannot be used for
this service. Only a packet data internet access point
can be used. Your device asks you to select the internet
access point when GPS is used for the first time.
Hold your device correctly
When using the GPS receiver, ensure you do not cover
the antenna with your hand.
Establishing a GPS
connection may take
from a couple of
seconds to several
minutes. Establishing
a GPS connection in a
vehicle may take
longer.
The GPS receiver
draws its power from
the device battery. Using the GPS receiver may drain
the battery faster.
Tips on creating a GPS
connection
Check satellite signal status
To check how many satellites your device has found,
and whether your device is receiving satellite signals,
select Menu > Applications > Location and GPS
data > Options > Satellite status .
If your device has found
satellites, a bar for each
satellite is shown in the
satellite info view. The
longer the bar, the
stronger the satellite
signal. When your device has received enough data
from the satellite signal to calculate your location, the
bar color changes.
To view the positions of found satellites, select
Chg.
view .
Initially your device must receive signals from at least
four satellites to be able to calculate the coordinates
of your location. When the initial calculation has been
made, it may be possible to continue calculating the
coordinates of your location with three satellites.
However, the accuracy is generally better when more
satellites are found.
If no satellite signal can be found, consider the
